My guess is the word has spread and people have finally paid some respect to these great developers.
Lately games I have paid $100-$300 for originally are doubling even tripling in value.
Lately I noticed most people are after:
Dangun Feveron
Ketsui
Guwange
Pro Gear
Dodonpachi
Esprade
Dodonpachi Dai Ou Jou
Espgaluda
I guess I represented almost every cave shmup out there LOL

What is the general consensus to this Cave Mayhem?
