I found i nice game i enjoyed for a while . Its fun to play but once u hit like and "uber" faze it gets boring.
The game is called Terraria. I downloaded a "hacked" vers. of it but its like 5-7$ on steam i think.
( the hacked vers. lets you play on multi player regardles)
Heres a bit of gameplay for it :)http://www.youtube.com/watch?v=tFYmJmhpMAE&noredirect=1
If you like the game i can share the "hacked" one :P. Then we can like use Hamachi and have a bit of fun starting from zero.
Using hamachi will let you play multiplayer without needing to actualy buy hte game :)
