So I finally finish Duke Nukem, and here's my review:

So I do recommend it :)

For those who aren't as keen on Duke Nukem as I am, maybe wait a few weeks for a price drop. But that's not cause the game is bad or anything. It's just the fact that the game is likely to have a price drop soon as it's getting reviewed harshly for not being something it isn't.
