Not all, but a lot of dark side choices in kotor, renegade in mass effect, bad karma in fallout, karma in fable etc. As opposed to "evil" choices in something like Tyranny.
Would you feel differently about those games if they didn't keep track of your "karma" with an abstract point system?[/quote]
A little bit, but it's still this kind of system that resulted in not enough meaningful contrasting choices. I believe that if the game was build from ground up without said abstract point system the choices would be different and better as a result, not that there is anything wrong with choices that allow the player to be a sadistic psychopath, but it wouldn't be the only contrast to heroic options.
