Game Sack is still around eh?
Anyway, I don't think Beyond Oasis is overlooked, Legend of Oasis is(that game very rarely ever gets brought up by itself), but whenever you're trying to put together a Zelda-like or adventure game list for the Genesis, Beyond Oasis is gonna make it in a Top 10 or Top 20.
I guess the rest of that list is okay, but a lot of consoles and PC have a lot of 'Criminally Underlooked Games', especially when you don't do it by genre, year or system.
