Tere both buiding games plus if u wanna build stuff in fc3 you need the free map editor btw im working on a ultimatle life rp when its finished il upload it
by that logic
gunpoint is a sandbox game
sid meier's civilization is a sandbox game
super mario bros is a sandbox game
doom is a sandbox game
half life 2 is a sandbox game
who else thinks that these games ain't sandboxes
