lvl 11 is when it starts to go downhill, all you have to do is spend your money right, buy a temple first and foremost, then buy a workshop, and don't spend anything until you get those two things and you can start ading on, i prefer the mana pool and then leave all my money towards keeping my 500 mages and 50 carpenters. some people like the archers though.
Yes it is very ezy!!!!
200 mages
150 archers
101 repair men
it gets boring after level 20
