Like most i will probably play dragons, i mean come on how often do you get to say your the leader of a draconian army?
if not that then it will be men
i like stable economy and defence
elves and orcs... not so much
elves are annoying, as long as their archers are not like extreme powerful forces like on most games (ESPECIALLY BFME2, grr stupid silverthorn arrows
orcs look to be fun to go savagely attack someone with though
