NVN 1 sucked arse, but as said, the expansion Hordes of the Underdark was actually quite good. The only truly negative factor (and also positive) was the focus on power-gaming and tweaking. True, you could proly walz through as a cookie-cutter warrior, but to get the most out of the game you needed a good char buildplan.
NVN 2 offered very good possible char builds, like my Wizard/Red Wizard of Thay/Arcane scholar with maxed out empowered spells and shit like that. You needed a good bplan though to get that wihtout gimping him with too many levels in wizard. I know the expansion storm of zehir was much appreciated by the community, I tried it but lost interrest in playing RPG's even though the game was pretty decent. It was poorly made though and lagged even on my comp at pretty low graph settings.
