TIL Shin Megami Tensei missed halloween by a day and was ported to the PC Engine on CHRISTMAS the following year lmfaooooooo
IDK what my top 5 would be, the Wikipedia seems kinda incomplete. They have SMT when mentioning Famitsu but don't note that it released that year at the bottom and the game count seems so small. I have to take a further look into it.
Try this site, it lists 687 games including untranslated ones.
