Yeah I prefer the longer Campaigns, playing games like Doom, Duke Nukem 3D and the first 2 Quakes, they all seemed to be 4 times as long as current video games. I used to play some old games for days or months to complete them, now it's like I can beat them in a day on their hardest settings. Problem is developers are too focused on Mulitplayer and pretty graphics and not quality of content these days.
Having selectable time lengths for MP would be great.
Quake 2 FTW man, I still play that, on the PC, on my XBOX, and my Ipod.
