I hope the RTS portions have an easy mode, since I'm of the "build a lot of tanks and roll over the enemy" school of RTS play.
I also wonder how the respawning of the Commander works. A simple timer?
And the Commander can spawn wherever your units can see? Assuming there's a proper fog of war and the AI doesn't cheat, I can see that being quite useful. Sneak a lone, stealthy scout behind enemy lines, then launch a dragon raid.
On the downside, having to decide whether or not to marry the dwarven princess before we even got to meet her or know what she's like? Not a very good move, I think.
Oh, and, I can already see me and the Undead Councillor are going to be the very best of friends.
