Halo's gameplay is worse. Its AI enemies are moronic and are glued to a small area of movement. Run past them and they simply don't pursue. Stand out in the open in plain sight, and they won't approach or even shoot at the player if beyond the spot to which they are glued. After all of the hype about Halo's supposedly great AI, I was shocked at just how poor it was even on the highest difficulty setting. Play the game how it's not supposed to be played by simply running past and avoiding enemies, and you can waltz through the levels (at least in the few levels I played before the game became such an excruciating bore that I stopped playing).
Thats great and all but my statement addressed Halo's repetitious levels vs. Doom 3's. If you've played both games don't insult what little intellgence I have by telling me Halo was MORE repetitious.
if you want to talk about AI features then....
Halo's AI would duck, use cover, fire, show fear, spout one-liners and overall be quite beleivable in the context of the game. Halo also had a far more interesting storyline (though i may be a bit biased as I'm a sci-fi freak). If the worst that can be said is that the AI in Halo stuck by their spawn/trigger area then fine.
Again, why anyone would compare these two games dosen't make sense as PK is more comparable.
