As a quick spoiler: Round 3 will probably have no theme/type at all. Of course, before you think it will be laughably easy to make a map then, mind that originality will still be very important, aside from fun gameplay of course. The mappers will have the freedom to do whatever they want. There's no worrying about putting cactuses in and stuff. But the map-rating is gonna be stricter than ever. So now, stop complaining about the current maptype (to some of you), and decide to join this round (round 2) or not. You can at least try to make an original map with flying vehicles. But keep trying your best though. We don't want to test maps that are doomed to fail. Maybe you can play Dodge The World Trade Center, Be A Bee Bringing Honey To The Sea, The Day That The UFO's Took Over, or Do A Barrel Roll - Press Z Or Arwing Twice! I'm just saying, flying maps doesn't have to mean 'Fly A Crappy SeaSparrow And Waterplane Through Some Checkpoints And Done' - that would not be a good idea.
