Here's a few 'mi old sausage' based on V1.0 experiences.

Macedon,
Easy to play- lots of money after econemy gets going, excellent all round troops(elite cav, pikes, flank support inf).
Ideal central position for spring boarding from.

Dispand excess troops, take out the Greeks then Phyros, dispand more troops, and build up on the money side of things, concentrating on Pella and Athens, build up the barracks, then the world is your oyster my son.

The Seleukids,
Semi-easy, abit epic from the start with all those cities, some of the ones in the East tend to get a bit miserable and want to rebel.

East meets west culture, the best combined armies in the game(only missing heavy horse archers, which I recruit above Armenia with a type4 gov).
Needs a careful balance of troops V's building up money making cities at the begining(get rid of expensive cav from the start).

A whole mix of potential enemies all seem to want a bite.
Attack the Ptolmies(spelling) as hard and fast as you can from the start.
