This.
This is what you're dealing with when you're not assuming dragon control. Dragon Commander is a fast-as-hell RTS, which was especially apparent during the brief multiplayer demonstration. Designer Farhang Namdar was on the base defense side, while his opponent (who he described as a "hardcore StarCraft 2 player") attacked.
Namdar's base was built and destroyed in just about three minutes, but it wasn't an easy fight. Both sides had to worry about resources and strategy while also engaging in dragon dogfights, so a high actions-per-minute rate is only part of the required skillset.
Color me daunted (kind of a purplish-gray, I think).
