Newbe Help

I just played my first game. But it would only let me buy infantry even though I had over 5000 coin. How can I buy the other units?

Maybe you hadn't enuth reforcements (the green number is the ammount of recruits you have...)
every three weeks they will be refilled...

I had between 3 and 8 in my cities. Even at the very outset of the game, all I could build were infantry.

I dont know... does it work now?

play the tutorial (one of the top right buttons in the game menu) or watch it on youtube http://www.youtube.com/watch?v=oX29SsU-7RM

maybe this will solve your problem...

OK. I forewarned you that I was a newbie. The YouTube helped a lot. I thought that since the unit type was grayed out, that it meant that the unit was disabled, in keeping with Windows standards for graying out buttons and controls, as opposed to meaning that I didn't have any of them yet. Sorry about that.
