Terraria is basically a two dimensional, Mario type, version of Minecraft. The retail price is $10 USD off of Steam. There isn’t really much to say, after testing it, except that apart from a few minor differences it is extremely identical to Minecraft. (I am aware that I have said that three times already).
Terraria has a lot more zombies and “mobs”, and they are a lot more violent. The days come and go very quickly and crafting is made very easy because all you have to do is go into the setup and craft from there, without having to remember those annoying crafting recipes.
This game would be a fantastic substitute if your computer cannot run minecraft.
Well worth the $10 if you like survival games.
