I haven't beaten it yet, so this isn't set in stone...
But so far I'd say the breakdown is (for me anyway)
Fun Factor - 9/10 (I'm really enjoying this game)
Graphics - 8/10 (Character graphics are a bit weak in my opinion, but environments look awesome )
NPCs - 7/10 (Pretty good - Not PS:T good... but at least KotOR good)
Rules - 6/10 (But things had to be changed to go from PnP to PC so this one doesn't matter much to me)
Stability - 8/10 (A couple bugs that are easy to get around, no crashes or major issues - For me at least)
Story - 8/10 (I'm enjoying it)
Music - Pass (I turn off music in the hopes it's improve performance... I do this with every game so don't read too much into it)
Voice Overs - 7/10 (Pretty good)
Improvements over first game - 10/10 (The first game bored me to death - I'm posting from the afterlife... honest)
Online Play - No idea.
