Terraria is out for the PC, Xbox 360, PS3, and Android and iOS devices. As far as I can tell, the Xbox 360 and PS3 versions have little to no difference as seems to be with Android and iOS versions. (Someone who actually owns the games on those devices will need to confirm.)
But the thing is that PC version is quite different from the console versions, and the console versions seem vastly different from the mobile versions.
I think we need something to tell them apart. How do we tag the different versions of Terraria?
