Excuse the pun, but I recently picked up the latest Humble Bundle for Steam and this was included. I know it's not a new game, but I went through a phase of playing lots of Minecraft back when it was still in early dev but got kind of tired of it. I never really cared for the 3D aspect of it, but Terraria being a 2D side scroller with 16-bit style graphics really puts it in my wheel house.
Curious if anyone else plays? I haven't had an opportunity to try out the Multiplayer mode yet, but I've had a lot of fun playing single player so far.
At time of posting there's still 3 hours left on this Humble Bundle, which also included Orcs Must Die 2 and a bunch of other great games all for the sake of charity so I highly recommend getting in on it while it lasts!
