Hopefully this is intended to generate interest in a new Rayman game! Rayman Origins and Rayman Legends were some of the best 2D platformers in recent years. Hell, some of the best ever, in my opinion.

This 30th anniversary edition looks like it’s basically the same thing as Rayman Forever, which is currently $1.50 on GOG. It’s usually $6. https://www.gog.com/en/game/rayman_forever

This new edition says it includes versions from 5 different consoles (missing the Saturn version though, which was a really good version), plus a “making of” video. So unless you care about seeing the differences on those consoles, I’m not sure if this new one is worth $20.
