Terraria is such a great game. I know its under the same light as Minecraft, but it's not a clone. It has over 2000 items, over 10 bosses, and over 30 sets of armour and over 200 weapons, as well as classes. That's just the vanilla game. It also has 15+ NPCs to help you on your way. It's also so great for building things since paint can look like one thing with the texture of another thing. All in all, the best game I have played under its light. Its also great since you can toggle blood off.
