When I was in high school, FPS that was all action and no story were my bread and butter such as Wolf 3D, Doom, Heretic, Rise of The Triad to name a few. Then in college I found out that FPS' could have good action with a good story, such as System Shock, Half-Life, Shogo: Mobile Armor Division, No One Lives Forever, Red Faction. I no longer settle for FPS' with no story, except to revisit an old favorite. Since the Duke Nukem series has never been known for having a solid storyline, I see no reason to think otherwise with Duke Nukem Forever.
As for my computer being too fast to run Duke Nukem 3D, the game just won't run for me on XP. Now if there was something like ZDoom, then I'd be interested in that and wouldn't bother with getting it on Live Arcade
