I have a friend (who is also a gamer) pursuing his PhD in Psychology. His dissertation actually revolves around how gaming affects social interactions, behavior etc.
During his research he has found that some people CANNOT process linear games for a variety of reasons such as:
Inability to accept authority or social norms - these types just get fed up if a game gives you strict missions or objectives as such they tend towards games that let them goof off indefinitely such as GTA.
Inability to accept loss or endings - these types do not want to progress a story as to avoid the risk of beloved character dying or town being destroyed etc. They are also reluctant for the fantasy to end, some of these people drifted towards mmos for this reason and have trouble finishing books or tv shows as well.
Inability to be immersed/cynicism - some are just unable to immerse in a game world to the point that they just don't care why the game is linear, they just see it as something being in the way of them doing what they want. "Why can't I go over there from the start of the game? Lost technology that must be discovered to unlock it? Screw that, this game sucks. Going to play Skyrim where I can just walk to wherever I want."
Anyways, some actually have a mental aversion to linearity it seems.
