I'd be down for a flash round, I'm checking the changelog religiously every day anyway. Whoever gets the third migrant wave is probably going to spend her/his whole turn doing housekeeping, though, since we're going to be all excited about minecarts and probably going to forget things like beds.
I agree that a succession game is not as nimble as multiple suicide embarks, as far as science is concerned. That's the point, though! We will probably screw up and serve as entertainment and preliminary research for the others.
I'm still excited. Depending on when my turn is I'd like to build the quarryvator- pulling ore up from the depths en masse to be worked. I sleep fitfully at night, imagining what it would be like to come up with something that will further dwarfkind- a warmonger quarryvator in every fortress! The smelters will run hot around the clock, and hopefully we won't need a bucket-line of peasants to keep it going.
I see no mention of powered tracks from Toady, though. We're going to need to do a lot of little tests regarding how momentum works- how long of a run do we need to get up a hill and around a bend? Is it better to have light or heavy carts? (Do heavy carts go slower? Do they keep momentum longer?)
Maybe I'm going to have to make peasants pull the carts.
