The Dkkanichron
This is the sequel to The Wrath of the Sentinel. Huge vistas... a very workable storyline... some minor problems. (I got trapped in a poly near the end and had to restore from a saved game, there are a few spurious walls, that sort of thing. Nothing major, nothing that'll ruin the experience for you.) Quite a difficult start, but once you find that first save buffer, you're okay. Very enjoyable. Comes with its own obscenely graphics-rich web page.
