The National Basketball Association playoffs are at hand and Playdom is taking full advantage with NBA Dynasty. This sim charges you with being the owner, general manager and head coach of your favorite NBA team. Unlike many games on Facebook, you have a level of interaction beyond clicking and waiting for things to happen. The first three quarters of the game are simulated but, during the fourth quarter of games, you have the option to coach the team. You’re trusted with three timeouts as well as first aid kits for injuries and sports drinks to get players back in the game fast.

Sega has already gotten its feet wet in the free-to-play sport sim category with Football Manager. Coming March 2011, Sega will launch MLB Manager, a free online baseball sim.

The MLB license gives Sega access to all 30 teams and 900 players that will appear in the game. It will launch in the US, Canada, Japan and South Korea.

If you collect five Independence Day themed items, you will receive a free Liberty Bell for your trouble. Apparently it’s so hard to get, FrontierVille players have taken to openly wondering whether or not the item really exists.

Since the free browser-based MMMORPG zOMG! started allowing players in 2008, it has been widely talked about in the forums. Guilds have formed to help others complete quests and meet other players who love the game.
