Hey guys (and girls!). Just wanted to make something a bit different so I figured I'd make this thread for sharing games on Steam that you think are really good but are pretty much unknown, hence a ''hidden gem'' game!
Now, getting to the point here, I'll start by suggesting a game that I really enjoy, which is:
Robot Roller-Derby Disco Dodgeball
It's basically dodgeball, but with robots! Surprisingly fun and is frequently updated too.
Now it's your turn!
EDIT: Figured I'd put Psychonauts in here too, I know it's been getting more recognition lately (The sequel was funded and all), but I bought it 90% off at the last sale and now I consider it one of the best games available on Steam. Can't get enough 3D Platformers =P
