Check this game out. It's pretty fun. I am bored as crap today, and I have 2 hours left, so I wanted to share this in case in anyone else is in the same predicament.
Been a while since I played that.. saved game is still there though. Only up to lvl 41, but the game pretty much just plays itself now.. my 750 archers kill everything before I even have a chance.
Drop one of the attackers into your castle and after a little while they get converted. Then click on one of the flags on your castle to assign them there.
