Although I do believe they have no intention of finishing the trilogy of this game, I would love to see it. It's storyline is very good, even a bit unique. The only two downsides I ever found in this game. One being the targeting system. Auto lock+FPS just does not mix for me. Oddly enough I didn't even realize till probably 3/4 of the way through it that I could lock on target for guns and not just powers. Other one being that the hard mode is mainly just more enemies and your biggest problem ends up being ammo.
Glitches are rarely a problem. I have yet to encounter one that either caused a real problem or happened more than once. Very stable game. I honestly find $5.99 lower than what it should be.
