I have done a lot of reading, and I see there is not one strictly definition for RPG, is it table top, PC or console. different people see it differently. The whole thing is even more complicated as developers while being in the process of creating better games start to mix genres.
And as for the games with separate endings I can recall only two. Deus Ex and PST. In both games there was no difference, how you play, what allingment you have, all these different endings were coming from choosing different approaches in the final scene of the game only.
