I'd settle for nothing less than totally realistic weapons system and system modes with supporting procedures such as MRS updates and maybe boresighting modeled extremely accurately. Also, contrast, gain, focus, etc. for thermal and daysight optics would be nice as well. Realistic ballistics are a must, scratch that, given, a long with extremely realistic damage for modules such as GPS, TIS, LRF, ammo rack etc. An ability to connect to DCS would be nice, and DCS CA would probably be the engine for such a sim, giving it built in air support. Destructible environments... well, for a CA-attached sim, ask the developers of that. For an indie sim, such as America's Armor, hell to the yeah! This includes aesthetic damage on the tanks, correct? The maps... Black Sea is big enough, indie game's maps would probably have to be gigantic for me to be remotely impressed
. Also, forgot to metion, 3d interiors are a must, loading animations would be nice. Also, if the tank in real life is equipped with datalink,( BOWMAN, Challenger 2; IVIS, M1A2, A2 SEP )it would be excellent if that were modelled as well.
