Hmmm...Izzy. Nope. I'm not really pleased with her because she's got two very powerful things: citadels and obviously, the broken Conquistadores. That'll feel like a beeline to MT just as, like, almost all other games.
What about something pure? Sid leaderhead. I never played him (nor most of here I am sure), but I think he doesn't have any starting techs, no traits, no UU, no UB, basically, a no flavor leader. No surprises, it's the leaderhead chosen for the tuto. I don't think it was for play. We arrange the strategy around what the map gives and not around flavors given to the chosen leader.
Of course, it's up to all of you. Anyways, I am glad I triggered the momentum for attempting something new in the mapscript department. And, I also back up Kossin's suggestion because it gives a nice feel regarding chokes and variety.
Regarding your past question, IIRC, water tiles aren't counted towards land target function.
I'm in as hinted originally.
