This game would be better serve as a online only title much like how Warhawk is. Instead of jumping on to planes you jump on dragons. Instead of tanks, how about riding one of those huge rhinos? Instead of lame AI soldiers, how about real players running around the battlefield on foot. A online only team deathmatch? Yeah, that would rock since the scale of the battles is already huge.
Now going for the real game itself, the soldiers on the ground doesn't dig it for me. They are always in line formation from far away and suddenly when you close the distance and land, that's were everything starts moving. Running over a bunch of soldiers will get old very fast. It's seem that the dragon is immune to any attacks on the ground and there is absolutely nothing the soldiers can do anything about it.
