Yep, I think I can say in my opinion Duke Nukem 1 > Duke Nukem 2!
At the risk of getting too far off topic, I’d probably say that the controls and gameplay just feel tighter, the levels are more creative, and the graphics are more fun.
To get back on topic, Halloween Harry’s controls seem tighter than DN2 and the graphics make better use of the pallette. On balance the level design is probably equal between Harry and Dukem 2, but the jetpack makes them much less frustrating to navigate.
