the new A&A is a kind of mix of turn and real time , maybe ya like it, and there is the classic RISK 2 game, turn based but not yet ready is Galactic Civilisation 2 really good, made some posts there too, check it out on http://www.galciv2.com
It will be in stores (hopefully) this month
Civ 4 is good too, many changes since 2 or 3, you'll like it, and if you did not the first 3 than you should give it a try anyway.
Somekind of turnbased rpg is : Smuggler 3 ,interesting concept
And of course don't forget the old age classic turn based strategy game:
named simple chess :D
I also like 'half-turn' games like Paradox-s : Europe Universalis series , Victoria, Hearts of Iron 2
