I would say YouTube is a great resource for finding games, especially the video game library channel. If you prefer more curated content you could check out gamesack, metaljesusrocks and other channels like that. For playstation 1 games i highly recommend a smaller youtuber called Sean Seanson.
You can also try googling "best SNES games" or other consoles, and you'll come across a bunch of "top 20/50/100"-lists.
I'm not at my computer at the moment, but I can try to put together a list of some games later
