Seibu Kaihatsu's Dynamite Duke (1989), a pretty novel hybrid Cabal-like/Beat-'em-up with a lot of love put into it. The arcade version's got a pretty slick art direction, the environmental destruction vfx rock, and the animation's pretty slick. The whole thing's got that passion project charm to it. Unfortunately, Cabal clones were only really in vogue in that late '80s/early '90s space, and the beat 'em up gameplay isn't fleshed out or consistently applied enough to be satisfying in a post-Final Fight, post-Streets of Rage world. I'd like to see something like it, but there's no way to bring Duke into the world of modern game design practices without drastic reformulation at a minimum.
Notably, Seibu had really high hopes for Duke, being a passion project and a intended magnum opus. Unfortunately, lukewarm reception brought in poor returns, the company slipped into dire straits, and they were forced to make something simpler and lower stakes as a hail mary. That title - a simple, Toaplan-esque shooter nobody had any real faith in - turned out to be Raiden, which would become a darling in arcades, pushing 17,000 units solds worldwide in the first year after release, and becoming the fifth highest grosser on the Japanese market in 1991. (Beating out some offerings from much bigger players like Konami)
