In terms of design and content updates, Terraria was a very PC-centric game to the point where I was rather surprised to hear that it's coming to PlayStation Network and Xbox Live Arcade. Pleasantly surprised, I might add -- this is a great way to reach people who would otherwise never play.
The more you get to know Terraria, the more you discover that it really is its own thing, contrary to what first impressions might suggest. That's highlighted well in this trailer for the console version, which doesn't take too long to crank up the insanity. Hell, I don't even remember encountering half of this stuff.
