I’m going to keep adding more items as I think of them in case others might be interested in this type of game.
There’s a free game on steam called Nightmare Kart which started out as a Bloodborne Mario Kart but the developer was getting too much attention so he removed all the explicit Bloodborne references that might get him sued and released the game as a vaguely Bloodborne-ish kart racing game. It features PS1 style graphics.
Apparently this game is getting a remake on steam, called Night Slashers: Remake. I actually had no idea this game was being made until I googled for the arcade game’s cover art just now.
