This game in particular is a stand out as not many games were released with this art style, this much gore, etc. I have no idea why as it was seemingly popular upon release.

I agree, the graphics are awesome. I figure the release of older arcade games would eventually pick up as releasing old home console games individually was always an option companies went with.

There are a few other arcade titles like this that we may never see re-released - Night Slashers is more like Final Fight and Streets of Rage while Mutation Nation is also but it has a more cartoon look to its gore-fest.
