What do you think is better?
I've seen Terraria, but never played. I have a copy of Minecraft though. I find Minecraft more fun, but if you have Jesse Cox and Total Biscuit playing Terraria, it's hard to choose.
Minecraft straight, more.....elements of fun.
Overall it's a great game, I have only been playing since Beta 1.6 but I have enough experiance to tell you what to get.
I have minecraft(ever since alpha) im gonna get terraria to play with my friend. Yeah i love minecraft.
