A social network game is a type of online game that is played through social networks, and typically features multiplayer and asynchronous gameplay mechanics. Social network games are most often implemented as browser games, but can also be implemented on other platforms such as mobile devices.

 GamerVision     - Gamervision LLC operates as a social network for gamers. It offers video game information, such as video game reviews, news, previews, video interviews, blogs, groups, forums, and other editorial content. Gamervision LLC was founded in 2001 and is based in Doylestown, Pennsylvania. Gamervision was founded by Fred Bauer and Edward H. Cohen, who’d been in the entertainment industry a while. Bauer and Cohen dreamed of making a TV show that, like shows that highlight music videos, would highlight video games, but when the Web 2.0 “revolution” happened, they changed strategies. The website has picked up a bit of a following from word-of-mouth (or word-of-keyboard) between gamers and from several of their videos going somewhat viral.

The site has reviews, articles, discussion forums, and even videos — some informative, some downright silly and occasionally hilarious.

The newest  feature of the website is “Swap and Sell,” which provides a board with a dead-simple interface to allow gamers to post things they’re willing to part with and what they want in return, either in the form of games or money. Gamervision only makes the connection, leaving it up to the users to complete the transaction (they will have a feedback form to allow people to build good or bad reputations based on others’ experiences dealing with them).

GameFriends - Game Friends was created by a couple gamers for gamers and was tested with the help of several other gamers. Game Friends is a sortable checklist with badges. The badges can be a checkmark, a smilie, a rocket ship, or dozens of other choices.

Stay on top of your social gaming and keep up with all of your gaming friends using Game Friends. You can have as many lists as you like; one for each game, one for each circle of friends, or one for each quest or level in a game. Copy the names in an existing list when starting a new one or import any number of names by pasting them in.

Add notes to individual names. All new look for iOS 7. Usability improvements across the entire application, cleaner look, more modern badges.

Gamerbio – GamerBio is a dedicated social networking community for PC and console gamers.

Gamestrata – GameStrata, is a social network for gamers who was launched in Silicon Valley. It’s a bit like Microsoft’s Xbox Live, only cross-platform and web-centric. GameStrata has signed deals to publish player stats of several popular games, including Activision’s Guitar Hero 3 (pictured) and EA’s Battlefield 2, and in a smart move that may make it the universal social network for gamers, will feature player-driven platform stats from the Xbox 360, PS3 and Wii consoles as well. Users of the top-ranked online social network can now set up leaderboards for their Facebook friends, display their game statistics and full gamer profiles on their Facebook pages, and compete against the entire Facebook population. GameStrata plans to support game tracking for more titles soon, as well as on newly available development platforms including MySpace and Bebo. GameStrata members can use the site's broad array of game-tracking tools to analyze their own skills, and share their stats with friends and competitors.

Before you can create and edit pages you will first need an account. Simply click "Account" from the upper right hand corner of the site and then choose "Create account". You will receive a confirmation email that contains a link you must click on to verify your account. Once verified you can start contributing to the site. To create a page simply search for the page in the search bar at the top of the site. If the page does not exist click the "Create Page!" button to create it. Keep capitalization in mind when creating a new page. To edit a page simply click on the "Edit" button at the top of the site. You create a custom title by using the {{DISPLAYTITLE:YOUR CUSTOM TITLE HERE}} wiki markup. You can view the source for this page to see how we used a custom title.

Creating a Custom Meta Description

A custom meta description can make your page look better in search results and possibly get more people clicking on it. Your meta description should be very relevant to the content of the page or what your page is about. It should be human readable and make sense to visitors trying to get a quick feel for what is on the page. It's good when your meta description contains part of the title and any keywords that you feel your visitors are looking for. Best practices say to keep the description between 150 and 160 characters in length. Any more and search engines won't show it all and any less you probably are not saying enough.

Creating a custom meta description on your AboutUs page is easy, simply use the following wiki markup anywhere on the page:

{{#description2:YOUR META DESCRIPTION TEXT HERE.}}

Before you can add an image you must first upload the image. To upload an image go to Special:Upload, click the "Choose File" button, fill in any extra details, select the image to upload, and then click the "Upload File" button. You will then be taken to the image's page. To use the image in a page that you are creating or editing you use the [[Image:file.jpg]] or [[Image:file.png|alt text]] wiki markup.

Warcraft Social – World of Warcraft right now is the front runner in the MMORPG market. Bolstering over 12 million players this game is definitely not for the loner. Unless you plan to multi box a batch of accounts, most activities in World of Warcraft will find you having to work with people in one way or another.

Most actions in World of Warcraft require teamwork and cooperation. Then again that's part of the fun - meeting new people, doing things you alone could not do, and having fun (sometimes not so fun) experiences.

Group Parties

Groups can be of any number and of any place. Say you are questing and you see a quest with a group tag. Then you can simply travel around and or use the general chat to ask around for help. In doing this say two other players show up needing the same quest. You guys make a group to get credit for killing/looting the same mobs. This is the start of a group or party.

Glinkster – Glinkster is bringing the social web into the gaming community via its own social network.

The Glinkster portal is as simple as it gets in terms of overall portal design. But it compensates for the cool features you could possible use in the social networking site. Here are 4 major cool things you can do at Glinkster:

1. Glink it – vote for links you find on the net that is related to gaming. That link moves up the Glinkster page as soon as other members link to it. So, the more member glink a particular link, the more relevant it becomes to the gaming community
2. Social bookmarking – Think of Digg or Del.icio.us with a specific niche which is gaming and that’s how Glinkster’s social bookmarking is all about. You can create and manage your own social bookmarks consisting of links that you have Glinked
3. Tagging – Yes, gamers know something about organizing information through Tagging too. Gamers know about tag clouds and the importance of tagging cool gaming-related stuff for easy access by their fellow gamers later on.
4. Accumulate Glink Score – You can up your Glink score by submitting relevant links to Glinkster. The more relevant your links are, the higher your score becomes. Once the links you submitted are linked to by other members, your Glink score increases as well. Think of it as a member voting system whereby members increase the reliability and reputation of other Glinkster members by the links they submit. Did I lost you there? Well, don’t mind what this Glink score is about yet. You’ll soon understand about it once you become a Glinkster member and start “Glinking” relevant gaming links.

Playyoo –  Playyoo is a social site for mobile gaming. Game developers can show off their wares and interact directly with the people playing them. Developers with existing projects can simply port them over with a Playyoo-supplied template for Flash 8 Pro or CS3. If users find a game they like, they can download it to their mobile phones free of charge. The entire service is run by advertising, which shows up both on the site and on the games when you start them up. Playyoo currently supports a pretty massive variety of phones. It's also nice enough to let you know how many games out of the entire library your phone can handle, along with providing a bandwidth limiter you can set to automatically cut you off of after burning through a set limit of data.

Playyoo has a 'game stream' that's similar to Facebook's newsfeed. Don't like a genre? Just get rid of it, and it won't show up in the list of games.
