Terraria is a great new game available on steam for only $10! It’s a 2D platformer with sprite based graphics and a sandbox world similar to minecraft. You mine various minerals and resources and combine them to build new items which in turn let you do more exploring. During the night time, if you’re not in a secure shelter, you may be set upon by zombies, snakes, giant worms, and demonic eyeballs.
One of the neat things about Terraria is the sheer scope in the size of the world maps. Everything on the map can be modified and customized as you play. You can dig and mine the ground and build building and castles and much more.
In Terraria, there are 3 map sizes, and to give you an idea of the difference in size between Small, Medium, and Large, here are 3 fresh maps I just generated. I warn you though, the image filesizes are pretty big!
