If you're going to metagame you should at least max out levels in Red Dragon Disciple. Totally unbalanced. Just start off with 1 level of Bard with high intellegence and level as a fighter from then on. Once you hit level 4 you'll be able to take RDD and watch your stats get buffed permanently. It comes out to about +8 strength, +2 con, +4 charisma, along with all the immunities and abilities that a half-dragon gets and d12 hit dice. As long as you've got 16 int you can max out 5 or 6 skills as well. Best way to RP through MotB.
And as long as we're on the subject of BG2, I'll turn out the
Unfinished Business and
Ascension mods, which really improve Shadows of Amn and Throne of Bhaal, respectively. Ascension is really only for those who know BG2 inside and out as it ratchets up the difficulty nearly to the point of unfairness at parts, but the way it changes the end of the game is awe-inspiring.
I'm pretty sure I liked NWN a lot more than the sequel. I don't quite remember why because it's been a while since I've played either but the first one had a certain draw to it that the sequel lacked. I'm sure it has to do with the change in developer. Not that NWN2 isn't pretty awesome, it just didn't wow me like the first (and it's awesome expansions/mods).
Really? NWN2 was pretty flawed, but compared to vanilla NWN it's quite an improvement, design-wise and story-wise. As far as the expansions go, I'd say MotB is better than any of the NWN expansions. I don't know if I mentioned it before, but
even the poison heart of CRPG fandom has love for that game. NWN was actually the start of the, uh, more "academic" players like those in the Codex turning against Bioware in a big way.
