SupCom 2 actually. The scale in that game is fucking enormous. But truth be told, i think the nukes are a bit small, as a proper nuke today (read: Czar Bomba) has a fireball with a diameter of like 4 km (and don't even get me started on the blastwave), which could easily wreck a large part of any map in SupCom 2 as far as i know. That would be rather overpowered, though. :U
