tl;dr Duke Nukem: The Later Years
A silly, ambitious little shooter that operates well (for its scope) as it includes a multitude of aspects. Maybe it was big/semi-big back when it launched, but I find most of it laughable yet enjoyable.
As a game, it operates with some clunk, but thus far, it hasn't been anything serious. Movement isn't exactly smooth, but it works, and inventory system has proven less than ideal, but again, it works. The HUD looks nice, but I'm not sure it's all actually "useful." The vehicles could handle better, but then again, I wouldn't expect vehicles and sprawling environments in a corridor-shooter that this game appeared to be in the prologue.
Some of the aesthetics and concepts like the HUD were probably phenominal back then, but basic polish is also not present. Still, if you can overlook graphical oddities and over-the-top gameplay elements (e. g.: the pseudo-realistic jerking of bodies as they die), you might enjoy this title.
I'd save my recommendation for shooter fans, or possibly Rambo-action movie fans. I'll likely update this when I've played more of the game. In the end, at least initially, it's a cheap thrill and I'm happy I purchased it.
