I still think NWN - while not exactly perfectly balanced - still has reasonable balance, to the point where you can finish the game with any class. Of course, classes like Sorcerer or Paladin are easier to play than, say, Ranger or Rogue, but that kind of imbalance exists in any game; in fact, NWN2 - while being based on the same SYSTEM, AND being a party-based game, was balanced much worse than NWN was. The Witcher, on the other hand, doesn't make an issue of balance, it just makes skill allocating redundant and any choice other than morality obsolete. There goes character development, right into the same water character creation jumped in earlier.

I believe we have had opposing experiences with NWN - our difference in opinion must stem from that - but still; if you feel that way, perhaps you should try it again and see if it still is that bad for you? It may also be your D&D background preventing you from enjoying the game - if so, there's nothing to be done.
