The original campaign is full of glitches. I just experienced a game-breaking one (near end of Act I), and cannot continue. The story is uninspired and boring. The quests are the worse kind of fetch quests, and they feel completely unrelated to overall threat, which itself is vague and undefined, at least through the first act, where my game glitched. The maps are boring and mediocre, like the rest of the game. Most maps of the outside world are just paths you follow, meet a few enemies, then continue on the same path until the next map. The combat is not satisfying or fun. So what if there are more classes if they're all the same as original NWN classes and overall boring to play? This isn't a good game. It's another overrate Obsidian mediocrity. If you have standards, skip it.
