It would certainly be interesting, especially when you consider that while DCS is a simulator... so is ArmAIII, and they have aliens available in a paid DLC (Contact). Funny enough, it doesn't divide the player base at all. Matter of fact, it even added stuff that people liked (weapons, vehicles, strange looking devices, etc). The same could be done with DCS. Realistic or not, it would add a much more _fun_ element to the game at large. A team would just have to figure out how to destroy an entire city, make it look good, all without cooking peoples computers
