I didn't played PS:T yet.but a Planescape game shoud be fine.
my suggestions are:a Ravenloft or a Dragonlance game

Guys guys guys...what about another Arcanum? (Or does Sierra own rights?)

Search for Arcanum right here on gog and check publisher section.

A PS Torment or Mask of the Betrayer-like game would be just fine for me...Avant-garde rp ftw!!

Chrono Trigger sequel! Once someone at Obsidan was asked if they were to make a game in a Squareenix franchise what they would like and they said Chrono Trigger sequel.

Sorry, I think that would be awesome... wee

Also, every single one of Obsidian's sequels were better than the game before it besides maybe Dungeon Siege 3 (never played any of the other Dungeon Siege games).

KOTOR II's story was way more cool even with an abrupt ending than KOTOR's. NWN 2 I found shitty but it was still less shitty than the shit I played called NWN (by far Bioware's worst game but at least the first NWN had a superior toolset). Fallout New Vegas was superior in a few ways compared to Fallout 3.

Alpha Protocol was way more fun to me than any other third person RPG shooting hybrid with its story and I even found the gameplay to be fun if too easy once you know what you're doing leveling up.

Also, about bugs, Bioware games have tons of bugs, so do Betheseda's. Any decent or better WRPG has bugs that I know of. Dragon Age 2 for the xbox 360 on standard TV's had every cutscene messed up and the problem wasn't even in the demo. Bioware's games have frozen before on me in the past and other problems.

Arcanum, Planescape: Torment, Fallout 1, Fallout 2, all had bugs as well as many of the other classics here on GOG.

Obsidian makes RPGs so why should anyone be surprised their games have bugs?
