raven software is seriously stuck designing games like it's still 10 years ago. ham-fisted overlong cinematics, level design that still has stuff like "a big hallway with no doors and an open vent at the end", etc. i think the last game of their's i enjoyed was soldier of fortune in 2000, when you could still do that. why they're id software's chosen lackeys i'll never know; though it's not as though id has ever known what a good singleplayer game is either.
God, you sound like a malcontent. They're FUN games set in cool worlds with classic shooter action, which most of us grew up on and still enjoy when done with quality.
