Well I just got done playing 3 games in a row on Sandbox and I had a blast. IMO the balance seems about typical of Halo maps, which I think is pretty good for most. I have yet to play a game on Assembly but I did do a quick little walk through last night and initially this is the map I liked the least. I got my ass handed to me on a few games on Orbital last night but that's not the maps fault, I like it.
I agree with Gergroy too that Sandbox alone does real well with all of the Forge potential. I have not messed with any of the maps on Forge so I can't answer about the mongoose racing.
