Depends on what you're looking for, and different rule sets have their positivies and negatives. The freedom to just "do whatever you want" and max out in every possible ability can be fun at times, but it's not very realistic. In the fantasy genre, it's not typical that Conan suddenly decides he wants to be Merlin. I can see why it would be a good game mechanic to allow in single player games though, since people get attached to their characters and don't necessarily want to start from scratch just to see everything the game has to offer.
NWN is, of course, real Dungeons and Dragons; and everything about the D&D class system is represented. There are ways to experience multiple classes in one character, but there are rightly downsides to making that choice. D&D is about having balanced parties of characters, not having one "god" character that can do everything.
