Quake's combat is sooo much more fun than Duke's I'm sorry. The enemies in Duke and Quake both are more aggressive than Doom's, but Quake's are way more fun to fight because Quake understood you actually had to pair that aggressiveness with the player having snappier movement and combat abilities.
RichardScrew whatever today's discourse is, time to dust off some 30 year old discourse: www.youtube.com/watch?v=nEDP... Duke wins because: a) more fun, b) the Duke says stuff like I'VE GOT BALLS OF STEEL, c) highly interactive levels that look like actual places and not just brown, poorly lit geometry.
