the art style didn't help the game, even with all the use of normal mapping trying to hide the low amount of polygons. I liked the outdoors landscape of Mars though, when you travel in the cart over the planet's surface.
And the overall rounded shape of the pistol.
Still a very iconic game, I completed it several times, but never completed the expansions although I started to play them. It was an impressive game for the Xbox. And I had more genuine fun in the second playthrough when I had the soul cube.
What I missed the most compared to the originals is the hordes of enemies.
It's an iD game from the Carmack days and it shows. Artistically it is a bit bland in many ways, though graphically impressive. Doom 1 and 2 weren't that great artistically wise, and some maps looked horrible. But if you combined the right textures some maps looked nice. Still, Quake 1 is imho the pinnacle of yesteryear's iD Software. artistically wise, it was so inspired that it doesn't look like a iD -or Carmack- game.
