I know it may seem a bit overdone, but I think a modern combat simulator would be epic. Think of F15's, Typhoons, F-35, A-10's, Su-27, etc. I think you guys could make it work as GSIII was a step in the right direction for dogfight simulation. I also think a team balancing mechanic would be great, as that was a problem in GS3 with too many choosing American forces, and Vietnam had like 2-3 people only
