Maybe there's a public for these games?
I admit I enjoyed both Double Dragon IV, and Stay Cool, Kobayashi-Sas!: A River City Ransom Story.
And, I like the "fake", retro 8-bit style (usually actually better than what could be pulled with original 8-bit hardware) featured in games like Mega Man 9 and 10, most Inti Creates titles, and Shovel Knight.
A clean, decent pixel art "retro" look, with smooth gameplay, fits well with beat'em up and platformer games, in my opinion.
But why that pseudo NES 8 bit style when we could have Double Dragon Arcade 8 bit style? When Double Dragon Advance exists?
There is an audience for good beat'em ups, too bad most current developers do not know the difference between a good one and a mediocre one.
I do not think that the game's visual design is the primary reason for how poor that game is.
It's one of the big issues, you have this huge 16:9 screen real state and its empty most of the time.
Honestly, I thought the pseudo 8 bit style was over 2 years ago.
After playing Prey and trying the Mooncrash DLC I was a bit wary of it being a pseudo roguelite, but after playing the first part I think this could actually work.
