Backlogger

Backlogger is a game organizer that lets you track your progress through your massive backlog of games. It doesn't matter which console it was released for. If you want to complete all your Game.com collection, or want to get through every game featuring poison mushrooms, make a playlist and queue it up to play next.
Now playing cards show game box art with an interface that allows you quickly update your progress in games, and see info about them.
Searches GiantBomb, an ever-updating database of games for filling in all the details about a game.
Allows for adding your own platforms in case you happen to have some sort of weird hack of a game released unofficially for a platform (like if you wanted to beat Half-Life on your iPod mini).
Make playlists so that you can create a list of games you'd like to play in any order you'd like. Make a spooky games list, or games in a series, it really doesn't matter what you do, just don't not make any. That's sad :(
Import games from Steam so you don't have to manually add them all in.
