Better than expected
The rest of your group are more like amusing sidekicks than anything else, since you get som much xp that you are the an unstoppable killing machine all by your self. The AI is also so bad for them that they tend to get in the way more often than actually help...
But even if there are severe drawbacks with implementation of the original rules and bad AI - the mood makes up for everything. Just imagine being a vampire born in the dark ages who fights his way through time for his one true love. Can it be any better?
If you care about clipping, AI and mouse control more than story, theme and mood. Don't play the game. Otherwise indulge in the good parts and overlook the bad ones.
