It is very tempting. But if I'm alone, I won't be able to play it just because I'm not guranteed to have access to Civ4 on a daily basis. Let me try to look for an alternative player, we will then share the responsibility. And of course, that'll be Russia and only Russia. Please, allow me 24-hours for that.
What is good about it is that the map is more or less known and initial planning stage is thus more clear. IMHO, redistributing resources is not a good idea, since that original map is at least somewhat balanced for the gameplay. I'd stick with the original version. Regarding the number of civs, this can be probably just halved without much trouble. Also, iirc, the original map is a bit too big but there had been a somewhat smaller version.
It seems, I'll play either way, so just need some permanent substutition/alternative player. That is also a nice walkaround of the doublemove.
