Backloggery helps gamers keep track of unplayed and unfinished games in their collection. Add all the games you own to the list, and track how far you have progressed towards beating them. This will help keep you from buying many new games before having played the ones you already own, and thus make the most out of your existing collection. Or it can simply tell you how much you're getting out of the games you buy, and how your collection and playing habits compare to others.
Additional features include the Fortune Cookie, which will give you suggestions on what to play next by randomly selecting games you own but haven't finished; generating signature images for websites and forums, so you can show others what you're currently playing or have recently beaten; and the MultiTap to connect with friends.
Games are added by simply entering a name; there is no database of games running on the back end. This has the advantage that games can be added quickly and simply without having to search for them, and that all games can be tracked, no matter how obscure.
