Its a tad ironic that people here are complaining about the game being "old" when its anything but that. Its actually one of its biggest offences. Fans wanted an oldschool game. Duke is not an oldschool game, its a modern shooter. From what Ive seen, it has regenerating health, two gun at a time limit, canned animations and its linear to a fault.The only thing that's slightly dated are the graphics.
This. I usually don't get on the OLDSCHOOL WAS ALWAYS BETTER, NEW IS ALWAYS BAD bandwagon, but with FPSes, that, as far as I know, really has been the trend*. D3D was about big, explorable levels with lots of interactive bits, hidden areas, different approaches to things, an really interesting architecture. I've not played DNF, but the impression I get is that it could basically just be a CoDBlops mod.
That and D3D, if you use an engine mod that gives proper mouse aim, isn't... particularly outdated feeling anyway.
Also consolization isn't a valid complaint. Consoles FPSes having really shitty and overly straightforward levels is pretty new, as well. Metroid Prime didn't, by any means, have simplistic levels or dumbed-down mechanics. Neither did a lot of those obscure PSX FPSes that I love but nobody else has ever played.
* Sort of. More mainstreamish FPSes, yes. On the other hand you still get stuff like STALKER coming out, which thrills me. Also I think I'm the only person that thought the original Painkiller was really boring compared to like, Serious Sam, which it was basically aping, but whatever.
