Ummm, developers got better at their job and started designing FPS's that didn't require you to see recycled corridors Ad nauseam. Oh, yes there are still some out there being made but they aren't the norm anymore. Respect DOOM and Duke Nukem for what they did and how good they were at the time but also realize that they have been surpassed over and over again.Ibacai

wrong fps evolved for worse.... now it's the game tells you what to do/go.

duke nukem 3d you had puzzles and crap, hidden area's to find.

duke nukem 3d is far above the pile of crap you call fps today.

The FPS genre evolved. crazy-player

into fps like killzone2 where you take cover and shoot explosive barrels?

Getting lost doesn't mean its non-linear. It often means its poorly designed.Skittles_McGee

No it means you arent observant enough.
