that's RPGs. not adventure games. RPGs are about letting you tailor a character to your own preferences, so multiple paths are preferable.
Adventure games are not about character customization. They're about puzzle solving and while there may be many ways to solve a puzzle there's usually only one best/funniest/most interesting way to do it. Why bother with the rest?
If the game has multiple paths, then great. I'm only trying to list the reasons I've seen programmers from Telltale state in the past why we're not likely to see it. And it's not a dumb reason. Do you want them to work on more content you probably won't see or content you probably will?
