@Drakonya and @Kirito love the suggestions!
Currently for every LFG Game Room we support will show up in the My Games section. However we understand that doesn't define you as gamers! And the more games you can show you play, the more you can find like-minded gamers. That's the intent.
In fact, with our new system, we can pump out Game Rooms for you to find and group-up very quickly. Basically 1 hour of effort versus 5 days!!! We are extremely excited. However we need to eliminate some bugs and improve on some functionality right now before we add more.
But love hearing about games you'd like us to support. As you know: we also gamers and we've built FTW.in for gamers by gamers. I didn't even realize Guitar Hero!!!
