They make archival bluray, supposed to last 100 years. Ideally, I would make copies of my dvds and periodically test them and replace them. Or back them up on a raid system. But that's so expensive for all that I have.
I liked the Contra games on NES and SNES. For modern games I like the Far Cry games. Simple shooters with leveling and sandbox maps.
I have beej thinking of getting a laser disc player. I have a HDDVD and 4k players.
