I've been playing this casually since release day. It isn't captivating where you HAVE to play it, but it is very enjoyable. If it wasn't Duke I would probably class it as a general shooter. Because of it is, then I have to say fully worth the purchase price.
Multiplayer - Some servers/ppl lag bad enough if it unplayable. If you get on a server with good connection then it is a great throwback to the 'twitch' shooters of PCs that seemed to get lost with weapon spread and 'controller friendly' warfare. I doubt the game would be as good on console, but I'm loving the PC version.

that's a crazy tie in!

I'm waiting for bargain bin pricing.

^ yeah, that's crazy, and I don't get it. It's a video card. It goes inside your machine. What does it do differently? Does it have voice recordings of Duke one-liners?

As for the game: the 3D shooter genre is now ancient. You gotta do something to either challenge or raise the bar.

Be careful what you say about this... :no:

Duke Nukem's PR threatens to punish sites that run negative reviews

If I were a game reviewer, I would be terrified of being blacklisted by anyone who puts out such a high quality game as DNF. Playing through the first level of the demo was a chore, and I quit about 2 minutes into the second. With the cutscene after the first level, the game is exactly what I hoped it would be when it was first announced I was in middle school, and the game looks and plays as if the 15 years since then didn't happen.
