The boring side of me has only one wish: to finish all the maps we currently are making, and secure a stabile dev process for the next major front that we will do.
The fun side of me (if I could press some magical button that would auto-generate it without any effort whatsoever) would be to have a perfect monte cassino map, with an obliteraded cassino town, a moon-like and detailed hill with a bombed out ruin of monastery at the top. The gameplay would start in the destroyed town and then be a push up the hill for allies, preferably Polish soldiers or French, as Id want this to be the final push. Germans would shell and MG and snipe down the hill but would be gradually pushed up the mountain. Gameplay for infantry would go in "steps" up the hillside, with covers like small italian farmwalls, rocks, sandbags and german bunkerpieces. All trees and bushes would be dry, dead or burnt.
I would have a huge final fight inside the ruins of the monastery (anyone played Uncharted2? if so, like that firefight in the tibet town, linear but with places to flank and elevations to go up and down) even if no fighting took place there IRL.
(like some of the best rounds of RtR bf1942 monte cassino, ofcourse with a lot bigger and more destroyed ruins)
additional ambience like distant explosions, flyover planes etc would be all over.
