Re: Expansive's relative merit on higher difficulties: It's the same. Health and happy caps don't change with difficulty anymore. They did in Vanilla and Warlords, but BtS took that out.
Urm... I'm not sure what you're talking about exactly, but I just loaded up two BTS games, both with Alexander, one on Settler, one on Deity. On Deity, I got +2 health from difficulty. on Settler, I got +4. Are these the caps that aren't supposed to change with difficulty?
Anyways, if that's not what you're talking about.. You start with less base health on higher difficulties, and on said higher difficulties, lack of health often outpaces your ability to deal with it through buildings/trades. Expansive helps a *huge* amount in nullifying this, when for the early stretches of many games, it's simply impossible to do.
