Dude if you wanted a game that was all about fraging the sh*t out of guys in Death Match, Q3 was the choice. Sure we were beginning to move away from that towards the standard of today, 'tactical' shooters and mutliplayer that consists more of capture and hold then 'kill anything that moves.'
I would absolutely LOVE a game like Quake3 combined with the deep teamplay found in more modern games. A mix of RTCW/ET-style teamplay and objectives, Quake physics, weapons (not every gun needs to be hitscan, or bullet based!), hell, even Crysis vehicles.
I just don't find having to crouch/prone & ironsight every other firefight to be fun for me. You don't have to remove all that Quake stuff to make a game tactical.
Speed (referring to Q3 and UT style games) and tactics are not mutually exclusive.
