Whatever... Don't judge me!
Anyways, if you want to support Duke, I suggest the
Duke Nukem Trilogy, starting with soon-to-be-released
Duke Nukem: Critical Mass.
The Duke Nukem Trilogy is a slew of new 3D Duke Nukem games going to be released episodically for the PSP and the Nintendo DS. They say that they are going to "[take] full advantage of each platforms strengths," and that it will feature "3D Characters with Detailed Textures," "Multi-Player Action," and "Total Ass-Kicking Weapons." It's being developed by Frontline Studios, rather than 3D Realms, so you don't have to worry about that.
Jon St. John returns as the voice of Duke Nukem, which makes this game worth more than its weight in gold.
