I personally do miss the "retro feeling" in games of today, but that doesn't mean that I don't like any of the new (3D) games that appear. However, I have found an alternative platform that seem to offer quite a lot to people like me... GBA :-)
Btw, I still think that Quake I&II is quite mindless blasting action, and even though similar games can be quite fun, these games sucks (Even though they're available on the Amiga ;-) ).
