Well, I'm still really really short into the game. It's free roam like Minecraft and at the beginning all you can actually relate it to IS Minecraft, because it is until you have things except it's 2D and looks like FFV. lol. Basically, from what I can tell are differences from Minecraft is that this game has magic/spells/abilities (none of which you start with nor do I have.) You find them deep underground or in general by exploring. From what I heard. There's a hell of a lot more things to craft than there is in Minecraft. The crafting system is slightly different in that you don't do anything within a grid, you just have the items on you and stand near a workbench/furnace/anvil and press [Esc] to open your full inventory which also includes what you can craft. You scroll up and down and find what you want to craft and click on it to make it. Also, this game has more weapons than just a sword and bow. It also has boss monsters. I'm not certain if those boss monsters are apart of dungeons or what. I have no clue, but I've seen them in the trailer so...yeah. Basically, my opinion is that if Minecraft had the shit that Terraria had, then Minecraft would be way more amazing - or - Make this game 3D. Either or. w/e.
