I dig the OG slime, but not for DQ. Those goofy and cutesy monster designs are what attracted me to picking up the DQW and DQM games for my Gameboy, back in the day.
For me, it's D&D, especially the early era. I feel like it wouldn't look out of place in one of the Monster Folios, though plenty of those had Lovecraftian influence(if not directly lifted from the Mythos to the point of causing legal issues).
Man that game was huge for me. I was so clueless about how anything worked but I spent so many hours playing I made progress. I don't remember ever completing it, but it was a blast.
