oh come on dog,i was sort of pulling your chain but you can't tell me "they all look different" they are all subscribing to the basic of "explore around,chop some tree,build a house,gather more material,build more stuff" created by minecraft and reworked by terraria and it's so dang obvious that they all have to go under "no no dude,this game totaly isn't a terraria/dwarf fortress clone just inspired" one of them even goes as far as copying the 3D 8-bit visuals of minecraft!
