I really wish two things for Reach right now:

1.) Forge allowed more building blocks and less inclines. I swear, why would we even need 99 inclines in the first place? Then again, some people just randomly throw stuff in Forge World and call it a map, so I guess it depends on the user. I just wish I had more building blocks or that there were bigger sized walls (besides super-size-me Coliseum Walls).

2.) We could edit campaign and create our own encounters or something. I just feel like so much potential was lost in the game that could have been another step forward for the Halo franchise (and the gaming industry).
