I never got around to either of them, though I am tempted every time they come up in a steam sale. That said, they don't appear to have aged terribly well and if I'm brutally honest, the gameplay looks a little shallow.I never got around to the second one, I might try to get a used copy at GameStop one day.
And yes, Outcast was great and easily the best of the Dark Forces/Jedi Knight games. I know some rate Academy higher because of the improved sabre combat (which is fair) it still always felt like more of an expansion pack than a game in it's own right and I always felt the writing was much weaker.
