Looks just like minecraft, but in 2D. I'd rather play a better, 3d related game, like minecraft over this.
Just bought the game and I must say, it's pretty amazing. Even if the graphics isn't THAT good, it's still worth it.
Also 1.0.6 \o/
Not really. I'd have to say that the only similarities between them are crafting (and Terraria doesn't go in-depth in that compared to MC.) and mining. That's all, I guess. Terraria has more enemies, really, and not focused solely on surviving or crafting.
