Terraria

Terraria is a funny 2D hack & slay, jump & run sandbox game in which you can make your own character and choose what kind of difficulty counts for your character. In Terraria you can build houses to make NPC's live in them. Play PVP with other players, go on an adventure finding rare items and collect loot you can either sell or keep, and fight all kind of bosses and monsters. The world is your playground.
 * Softcore is the mode in which you respawn with all the items you died with except half the amount of money you had
 * Mediumcore is the mode in which you respawn without the items you previously carried.
 * Hardcore is the mode in which you'll turn into a ghost upon death. You can't do anything but watch the world or other players. Whenever you leave the world the character will be deleted.
