This is an idea that won't be implemented anytime soon if not at all, but I would be happy if a new island was added, one with skyscrapers and paved roads. It could be designed after a city like London, Berlin, New York, or some other city. There would only need to be 1 large airport on it, designed like JFK or ORD WITH taxiways and everything. It would also be cool to see a race track so we can make race cars (yes I know this is Simple PLANES, but I like to build cars when I get bored).

Also multiplayer would be a fun feature, now with the weapons, we [the community] could have large scale wars or just 1 on 1 battles or maybe tournaments.

Last, maybe work on physics with water so we can make actual boats. Make the explosions look more realistic and do less damage.

Thanks for reading this and have a happy new year! :D
