Terraria
9/10
Fantastic little platform, side-scroller 2D game. Very similar to Minecraft in terms of mining for resources, and crafting them into useable items. Loads of creeps that come after you relentlessly, providing you with the option of either hiding in your house that you made, or staving them off. Creating tools made from copper through to hellstone is exciting and adventourous. However, once you have reached the last tier, the fun dies down a little.
None the less, the game is great in coop and generally all round a solid game for $10.
