I think it's too small in that we haven't started colonizing our solar system yet. That's because you can't breathe outside the atmosphere. Then again have anybody actually tried? Maybe space air is good for us.
Anyway I was planning a world tour for myself, but when I looked at a map of the world, all I see from left to right is two strips of continents and two crumbs called Australia and New Zealand.
Exactly how is one supposed to be amuzed for long with that? I need more worlds to explore.
