@Uber, one of the reasons I chose not to have Schwarzenegger as the Californian leader is because of how recent he is, and the fact that he's still alive -- wouldn't feel comfortable making a judgement of history for him. And don't worry, I tried to represent as much of California as I could in 4 unique attributes: early colonization and exploration by the Spanish/Portuguese is represented by their Expeditionary UU, Ide represents the Republic; Muir straddles the border between the wild frontier and modern times as a conservationist, their UA represents the Gold Rush as well as California's continued scientific prowess + high GDP, and their Filmmaker UU represents the modern film industry and cultural influence of the state. While there is a lot more to represent, you do have to keep in mind that Civ is a pretty macro-level game, and trying to represent it all effectively is hard. I will definitely look at Palmyra, though, and if nobody else has done a proper one by the time I get the 3 civs I'm working on now finished, I might try to do it justice.
@Skaz, Scotland is still pretty early in the planning phase, and I could use some ideas on what needs representation, what sorts of uniques, etc. I'd like to have either Robert the Bruce or William Wallace as their leader (probably the Bruce just to dodge all the possible Mel Gibson jokes), and as their general focus, early-game warmongering/defense into late-game Tourism, somehow. Keep in mind that Scottish and Irish culture have a lot of influence with Americans at least, what with the bagpipes, and the Loch Ness monster, and the common hatred of England. Perhaps some sort of a Tourism bonus from defensive/military buildings? Defensive buildings grant a free unit from the current era upon completion? I'm not the biggest expert on Scotland here, so any sorts of ideas will be a big help.
