Theoclymenus: As an avid Infinity Engine games fan I still think that P : T is more linear than something like Skyrim. What is wonderful about P : T really is the depth of its thinking. The dialogue options in P : T are much more varied than those in any Elder Scrolls game but at the end of the day they are very limited when compared with an ordinary conversation with Joe Bloggs in real life. Planescape : Torment is a better game than Skyrim because it is deeper than Skyrim, but it is nowhere near as "non-linear". But Skyrim is still linear, even though it wants to be non-linear. There are no truly non-linear games.
drealmer7: Definitely linear and even the different endings aren't THAT different, but the variety of dialogue is why I listed it.
I haven't played it, but I feel something like Gothic is non-linear, but still all end up at the same ending regardless of the path you go, so, yeap.
Yes, sorry, the thread just got me thinking. I am currently playing Deus Ex Human Revolution, and while it is brilliant and polished it is VERY linear. In fact, without the side quests it would be totally linear, except that you can employ slightly different methods to complete each section of the game (which, of course, are arranged in a line !) It's a difficult thing to create a game which is both linear and creates an illusion of freedom. I think the Elder Scrolls games deserve applause for being the closest to achieving this goal. I don't think they are the best games of all time, but I think they deserve credit for what they have tried to achieve.
Apologies, btw, I may have downvotes your post by mistake. On an iPad it is difficult to get the "reply" button to appear, on gog, and it is right next to the the upvote and downvote buttons. Please feel free to downvote me to even things up ! Sorry.
