This game is nice, for a while. Eventually, people get tired of a game where your only real objective is to crank out as much gold as possible, though. Nobody likes to grind for levels or money, and that's entirely what this game is. Don't get me wrong, I like the overall feel of the game, but it could use more variety. Perhaps a PvP option?
