For a good example of FPS RPGing done right, look at Morrowind. The game did it well, without detracting from game play or the RPG element. There are, of course, hundereds of examples of RPG in which everything is \"Automatic\", however, I pefer the idea of Baldur\'s Gate: Combat and dodging are automatic, but you could run away and cast spells at your liesure (for the most part). Either way is effective, and I think either one would serve Plane Shift well, if done correctly, as Drilixer said
