I have the Planescape Torment/Soulbringer bundle. I played both games on Windows XP without any need to patch them. I don't know why the critics are not higher for Soulbringer. Of course, it is not as good as Planescape Torment, but I really enjoyed it. It is the first game that I played where you can use a weapon different ways and where combat is slightly different depending on the weapon you use.
Soulbringer as a known bug on Windows XP though and when I played, two years ago, there was no patch to fix it. Approximately in the middle, the game freezes during a cinematic. I was fortunate enough to have another PC at home with Windows 2000, so I took my saved game to that PC, looked at the cinematic, saved again and got back to my PC with Windows XP. This is the only problem I had with those two games.
I do agree with the suggestions made by other members. Planescape Torment and Fallout are my favorite games... after Baldur's Gate 1 and 2 of course.
Please be indulgent with my English, it is not my native tongue.
