Upcoming game with good potential, but everyone complains about it because the sonic fanbase is ♥♥♥♥. also leaks are already out over a week before release. >:-(

Really cool game!! Team up with the Classic sonic, to save the world from time disaster!

Second STH 4 game. Metal sonic is (FINALLY) back! He heads to earth to seek revenge on sonic. Now you can team up with tails!

a fun sonic game with slightly same levels from the past. Bring back childhood memeries!

So cool, you play as sonic and his friends to race. Going to "Undrivable areas", you transform into some awesome things!

Make cool movies using tf2, gmod, hl2, etc. Post them on YouTube and Steam and show everyone your movie!

such creativity. Learn a lot, and make the best things every! Warning: some achievments are a bit crazy...

Best horror game of 2014! You are a security guard, watching animatronics, and not letting them catch you. Has so much suspense!

The second portal game. More puzzles, more characters, better graphics, and MORE FUN!!!

A great puzzle game. You use a special "Portal Gun" to create vortex portals, which you go through one, come out the other.
