Personally I enjoyed the game play although I didn't find it too much of a stretch from the original. Sure, there were additional feats, force powers, the graphics I though were somewhat improved and the robes didn't look like wrapped skirts.
Actually, the only problem I had was the immersion factor. Every time I felt like I was getting into the game there seemed to be something missing, which seems to be a commonality. The ending just fell flat and there were a lot of unanswered questions. Especially considering the whole posse of saber toting lightsiders I had with me going into the final act, darksiders the second time around, the events surrounding both female and male PCs in regards to romantic interests, etc.
Though with a save game editor and jacking everyone's influence to max I was able to pick up more of the swiss-holed storyline, giving me some measure of satisfaction, at least, in regards to HK, G0T0 and canderous (I'm always amazed at how many ppl didn't recognize him from just by the voice... not to mention that he talks about Clan Ordo).
Personally, I'm anxiously awaiting the fruition of Team Gizka and the restoration project's efforts as I think that will finally tie the game into something more along the lines of what was intended as a final product than the plasma-torched job that became what was released.
Not to say that it wasn't a game on par with the plethora of other games out at this time, it just didn't come through as well as it could have, imho. Although, the release of badly done/incomplete/rushed games is something I think the industry should be held accountable for... but hey, they've got an "RPG of the year" title they can tout now so who am I to expect such?
