One thing I have noticed no one's mentioned is the spell system - is it the same as in the previous game? It evoked a few memories of Stonekeep for me, fiddling with runes to work out new spells, but I found it a bit fiddly for the middle of combat. Plus the optimal way to build a Wizard seemed to be one in which you'd be likely to have a single powerful damage spell which would be your mainstay, perhaps switching to Sparks or another starting-spell alternative for the rare enemies resistant to your favoured element.
It's mostly the same. Even most of the spells are the same with a few additions and one or two changes. The biggest (and best) change is that you can now click and drag to select runes, with all spells being changed to not have any unconnected runes since that'd be impossible with the new system.
In other news, I finished the game.
I was slightly disappointed by the "true" final boss, mostly because the Lindworm was a so much more entertaining fight. The Trickster/Island Master fight was just tame by comparison. Maybe it was the environs and general mood, now that I think about it, since the fights were otherwise not that different.
Finally I'd also put in a good word for the Might and Magic games. Only ever played VII and VIII, but man were those good. VIII was hilarious with potential Dragon party members and all the OPness that implies. VII would be an overall stronger game, though, in my opinion. I'm a bit sad that the series lost its sci-fi/fantasy backstory and general flavour in recent times, though. It was a really neat setting they had going and the state of the current games is incredibly bland in comparison.
