I haven't played Quake 4 in a while, but I did play a bit of DN3D just a couple of hours ago. What you call "annoying" I call "challenging" and I can tell you now that there's at least one level in DN3D that would simply be impossible to recreate in a game with regenerating health (episode 1, level 3 - Death Row). I absolutely relished the situation the game threw me in - you start the level in an electric chair taking damage (with zero prior warning) and you have nothing but Duke's Might Foot(tm) to extricate you from your situation. I can guarantee you that there won't be anything in DNF as remotely heart-pounding as that.shrekfan246 said:I'm with you on the last bit, but I honestly don't care about the other two. Have you tried to play Quake 4 recently? Sure it's not difficult, but it's annoying as hell to get through a firefight with only 10 health left and no armor and then have to reload from your last save because you went into another room and instantly got killed because you literally had no way of getting any health back (either by backtracking or trying to find a health terminal further ahead).
Yeah, regenerating health is unrealistic, but if anyone could heal bullet wounds by channeling the masculinity of their neck muscles, I'd expect it to be Duke Nukem.
And carrying only two weapons? Okay, admittedly, such a muscle-bound freak should probably be able to carry a small armory but again, it's not something that would break a game for me.
EDIT: What's even more infuriating is that it appears that several key design choices were made without being clearly thought-through or even properly implemented. The two-weapon system is probably the best example. In gameplay footage it is painfully obvious that the game frequently puts you in situations where you need a greater quality (variety) of firepower than you can carry at any given time. This is not good design, people!
