In further letting things go developments, I think if I had a NES and SNES games other than Castlevania 2, I found have found them in the basement by now. I think one of two things happened: Either my parents gave them to my cousin (giving things to relatives is the exception to the "keep everything" rule) who then sold them on eBay, as he does with all things or I foolishly took them to Gamestop for credit toward some Gamecube game or Max Payne or something stupid like that.
RIP, classic console games. It's a shame because music played by the NES just sounds way more bangin' than it does by emulator, in addition to the games feeling better.
