Nah - I lost interest in BG1 about halfway (yawn) and with that low interest level I never got anywhere close to ever buying BG2. I have thought about getting it one day, just so I can pester Donut by asking him how to kill Kangaax (sp)
(I understand he throws keyboards in despair at newbies who ask this question).
Ultima or Wizardry are both better series in my opinion - even the Ultima Underworld series.
As for the others mentioned above :
1) PST - rocks
2) IWDII - blows
3) Morrowind - intriguing but time consuming
4) NWN - good if you bought it for toolset & MP, but low to average on the SP.
5) Eye of the Beholder 1 & 2 in it's day really rocked (please don't anybody mention that there was an unmentionable 3rd effort by the game designers - some things are best left alone)
