Oh shut up and get over it! I got booted for like 3 days for stealing a post. I'm not doing that again, so back to topic.
I could see Hi-Tech releasing a different game altogether just for FPS action. I would be based on Aces High obviously, but would have it's own graphics and physics and all that, and would be its own game. The only thing it would share with Aces High would be the battles to take a base.
In other words, in Aces High... a Lancstuka hoard levels a town and gets troops into the map room. This would no longer result in an automatic base take... however it would start a 'mission' in the FPS game... where people in its arenas would get to join in on the battle for this particular base. And, the results of that FPS ground battle would be translated back into the AH game. Then, when it's over, the people in the FPS game would go back to their massive shooting chaos until the next map room is taken in AH.
