I've got $7.49 in my Steam wallet right now and want to spend it. Looking for multiplayer but open to anything. Go.
Garrys mod is on sale.
The Binding of Isaac is $4.99 and is a PC classic. Super Hexagon is $2.99 and is a super fun and crazy game. VVVVVV is an indie platformer were you have to control gravity to get past a lvl, its only $4.99. There are many more but you should just head over to Steam Store and look at some of the reviews and decide which game you like or (just an idea) wait a few til the next big Steam Store Sale (probably in spring) and get a bunch of game super cheap :D ! Good luck
Ftl is very good if it is under 7.49 I would pick that up.
witcher 2 was $3 this weekend.. dont know what it is now
