I've played this game more or less exactly the way I would play a DnD game and I've had no problems with the difficulty. I think a lot of DnD players are too accustomed to going at problems and fights head-on rather than addressing them tactically. I would suggest easier difficulties for players like that, so they can play their way and still have fun; if I were DMing for a group like that, I would certainly adjust the challenges to their playstyle rather than demand they change how they play to suit my challenges. Right now there are no difficulty settings, but I'm pretty sure there will be. That should prove an adequate fix.
