It's hard to answer something like that, because, quite simply we don't know yet. Because the game has not been released yet, any queries into the quality of the game would be pure speculation. It would be like asking in January if E:TW was going to be better than M2. SOme could speculate that this or that might be improved, but at the time we had absolutely no idea if E:TW was going to be a boom or a bust.

Furthermore, so much of that stuff relies on personal opinion and preference, that it is really difficult to put a stamp on any sequel saying it was better than the last. You may say that R: TW was the best TW game around, but I know there are people who claim E: TW is the best around, or still others who solely play M1 or S: TW.

Really what I'm trying to say is that we really can't say anything for sure. All you can do really is have patience, and come to your own conclusions when the game inevitably (I hope?) comes out.

However, one thing can be determined right now. That is that when this game does come out, we know it will come with the quality and attention to detail that we have come to expect from this community.
