i think that there should be more sandbox maps, kinda like impact, but a lot bigger like a map as big as forge world but just space. and also a small rock or something to spawn on. i also think that bots would be a good addition as well, even in halo 3 i always used to wish that we could have army wars or something on avalanche. another cool thing would be the option to make objects destructible, so you could set a wall coliseum to destructible, then if someone shot a rocket or two at it, there would be a large hole in it. and maybe if you kept shooting, eventually it would just become a frame. but it would also respawn afterwards, or not if you didn't want it too. time adjustment would be fun too, or even set it to change the time every so often. and one thing that would really be awesome, is if you could grad a number of different objects at once. so you could build a frigate, or a spaceship, or even a rocket! then grab the whole thing with your friend in it, and make it fly round. but an addition to that option. would to set a bunch of objects to controllable. so like i said before, grab the ship or what ever you made, then set it to falcon controls, then get in it, and fly it like a falcon, or a banshee etc. (AI Benno98)
