I would make a city similar to an MMO, and then have unlimited AI people run around on it. I would also make a covenant battlecruiser with working glass gun, and then I would glass the city.
I would first cover the whole ForgeWorld with those decorative columns(time consuming yes so maybe I'll do 150 columns a day). Once every space is filled I'll save it as a template and then make huge maps by deleting pathways into them and adding ramps. =)
I usually run out of "building blocks" and "walls & windows" when I forge maps and have to turn to using inclines and bridges. So I would remake all my maps with the extra building blocks and walls...
I would make a map with lots of rooms of all sizes on different levels then cover all the walls, floors and ceilings in shield doors/walls and make a map thats absolute chaos with plasma launchers > I've already done something like that on Boneyard since there is so many shield walls and doors you can make on that level, once I get internet I'm uploading it and the gametype I made for it. I saw a map on youtube that had that concept but with only one room. Bright Blue Balls of Fury - YouTube
I would make theBest remakes using like tin cups for hills like Valhalla I tried to do that but I did not have enough tin cups.
You, my friend, are in possesion of one of the funnest toys in the known world. (Before you start building something, I recommend designing it so that as few units are shown as possible, as so to not distubr Build a realistic BTB match, as someone said earlier. A 10-part invasion match, designed to be just like a campaign level! Something so big, that when it sits next ot you on an airplane, you wonder whether it should've bought TWO seats. A very, very, very large, 16 scorpion war in the center of the Canyon. Your own personal redesigning of "Spire", to be a 2-team multiplayer match. A huge, huge, huge UNSC warship, designed so that it replicates the Pillar of Autumn as well as someone can. It doesn't matter, just forge something!
