Nice man! Single player is great. I've been doing custom battles just seeing the game engine, etc. What I do is do max army of archers vs max war elephants (the best unit), and just watch the elepants RAPE the archers (also other uneven battles). Let us know of anymore of these stratagy things you find. I got the prima strat guide, and it says if you flank in this game it actually matters. The way a unit if facing affects the way he takes the hit, if he is facing you its even, if he doesn't see you coming, he gets owned. I'm sure they're are a ton of others things like this, gotta read the guide more. For a $15 it's a good guide.
On a related note, I can't seem to get the multiplayer to work. I just wanted to see what it was like, will you guys tell me if your multi is working for you all?
