KingofGnG: I don't exactly remember the ending, but I remember pretty well that, compared to The Sands of Time (which I essentially mastered, gameplay and combat-wise), Warrior Within was frustratingly long and messy to navigate...
It's been years since I played it, so quite possibly these days I'll find the length a bit overbearing as well. I do remember that it was a long game, for the genre at least, but I liked every minute of it back then. I especially liked how you would travel back in forth in time to navigate the levels. E.g. a pillar collapsed to due age, so you travel back in time to when it was still standing so that you can reach a certain location.
Thematically however SoT I thought was the best., but mechanically it has aged too poorly for me unfortunately.
