How does NWN2 compare in this regard?
Depends which campaign you want to compare it with. While NWN2's OC had better party members and a generally more interesting storyline, at heart it was really just a 'save the world from the bad guys' story without any deeper meaning or theme to it.
Not to say it didn't have some moments or interesting characters - the haven at the end of the second act could've passed as something of Avellone's (though only stylistically), and the party member who joins you at the start of the third act had quite a bit of depth to him. There was also some amusing banter with the various companions, and various snippets of the game were enjoyable.
Bah, all my comments are coming across as contradictory. From beginning to end, I find the whole of the OC to be rather like this:
(Optional tutorial) meh. Start of game - pretty engaging. Pre-Neverwinter - still engaging, but definitely less so. Neverwinter - blah. Boring. Orc caves/Old Owl Well - why the **** am I even playing this? Oh my god. Blacklake District - things are getting interesting again. Ember - plot twist. Also later consequences to actions that currently seem trivial. Githyanki caves - very interesting and very engaging. Best part of Act I and the game yet.
Opening cutscene and start of Act II - definitely grabs you in. Pre-trial quests - mostly boring, in one instance annoying. Trial - very fun (it was written by Avellone). Prelude to post-trial fight - very good general mood. Assault on CRK - also done very well. Managing your keep - mixed blessing. I cheated in the required gold. Illefarn ruins - tiresome hack and slash, even more tiresome puzzle you must work with. Engaging only insofar as it contains details of relevance to the plot. <spoilered> location after that - sets a very good mood and adds depth to the plot. Haven - best part of the game. Avellone's touch was there, stylistically at least.
Castle Never - engaging. But the 'puzzles' with the statues were both unrealistic and uninteresting. Quests prior to battle - tedious, pretty meh all around. Nolaloth - pretty interesting. <spoilered> location after all the shards are found - excellent mood. If only it was like this in the more boring parts of the game. <optional spoilered area> - a rare moment where character development can take place, also worth doing. Siege of <spoilered> - all around pretty fun to do. Fortress of the main bad guy - extremely tedious, wearisome, generally pointless hacking and slashing. Final battle - done pretty well. Ending - terrible. Probably different for anyone who knows there's going to be an expansion.
One of the biggest grips I had with the OC, though, was how railroaded the plot was. There's very little player choice (and even less consequence) to it all.
For the expansion pack, I must defer to Vault Dweller's (excellently written) review (
http://www.rpgcodex.net/content.php?id=159). He's clear proof you can despise the OC and still enjoy the expansion. Personally I think it gives PS:Torment and KotOR II a run for their money. If you liked either of those games, playing MotB is a must. You can always skip the OC if you find it boring - playing it isn't entirely necessary. MotB is mostly independent of its story, which is all given in a summary to you in your journal anyway.
This has nothing to do with how bitter I am at having spent 2 hours running about Death God's Vault before realizing I was supposed to go back to the mortal plane and talk to the priest. Not at all.
I'd hope so... gameplay, however annoying or fun it may be, really isn't what makes a game what it is.
I just found the OC welcoming and enjoyable to play, even when surrounded by the forces of darkness. MotB is just one "Ha ha, you've been screwed over" after another.
Personally, I find the best stories are ones where the PC is tied into them, has a vested interest in their outcome and a general reason to say 'I care what happens. I have a reason to!' Whether it's Irenicus stealing the PC's soul in BG2, trying to discover your past in both TSL and PS:T, there has to be something the player has invested in the story or they have no incentive to participate in it.
Typically, screwing the PC over is what gives them that reason to care. It's really the only objective reason they have to. Part of what didn't make NWN2's OC as engaging as it could've been for me was that my PC didn't have any reason to care about the story. Yeah, Neverwinter and West Harbor could get screwed. But my PC was totally uninvolved in it all. (The shards of Gith's sword were, oh yes, but they weren't my PC.)
