Terraria. What an awesome game even though I just bought it. It's kind of like Minecraft, but it's side-scroller.
Unlike Minecraft, you spawn with a sword, pickax and ax, but I have no idea why they would make it that way. Why do you think? Did you know that you can get a raincoat from a zombie? so weird.
I wish I knew how to craft better weapons and armor. Do you know? My Terraria name is Warrior21, in case you wanna play with me.
How do you craft glass?
