I've gotten every achievement ingame, but because of bugs (and the fact you cant rejoin a guild) i have to start again to get the guildmaster badge. lame. Good game but far too many bugs.
the achievements reset whenever you exit (or a bug causes you to restart) which is very irritating when you're going for all of them (most you will reacquire once you log in, but some such as the guild ones you do not)
Excellent game, although it does get ridiculously hard.
I'd suggest adding in different difficulty levels - perhaps on the easier difficulties building prices don't go up so much
