Well I only play on pc and found the game pretty damn easy on normal mode.
I have to agree with this; however I'll admit that it took me quite a while to get the hang of the tactics system. Once you've cracked it, though, the game becomes quite easy. There are a few ridiculously overpowered spells (e.g. Cone of Cold and Mana Clash) that basically amount to an 'I win' button. I still quite like the fact that you could basically set up mini-AI routines for your companions; I just wish the system had been a bit more flexible and expansive, e.g. allowing you to set up conditional tactics. But either way it's pretty different to the turn-based system in D:OS, so it's hard to compare them directly.
