I have kept playing and just wow... I now own the tower and when you already thought the game was great, you realize there is even much more in it.
Not only is the game great, but the small nuisances other games have, don't appear in this one. Like lacking inventory, long boring traveling, and many other small details like those.
I just emailed my friends telling them that this is my favourite singleplayer rpg since I can't remember when. Over dragon age, fallout, and even oblivion.
I don't agree about the powerfull +X damage stuff though. I don't think it's only a matter of level. Yes, at lower levels it is even worse, since such item can make everything else worthless for 15 levels. But even in higher levels, this single mod is just too overpowered compared to the others.
Why would I want a legendary weapon that does lots of damage, sets the enemies on fire and leeches life, when my 15 levels old weapon has a +65 damage.
Even worse with dual wield. Just beeing able to equip a +65 damage and a +40 damage, beats any other stat on a weapon, including the damage it does.
