I looked up the credits for this game and noticed that the main guy who designed this game also worked on all of the Uncharted games and The Last of Us. I think the Uncharted games are actually the most like this game.
Generations Lost is an interesting game. To me it is not so much a cinematic platformer as it is a continuation of what was done in the old flip-screen platformers like Pharaos Curse ,Bruce Lee, Zorro, Conan etc (and maybe also Impossible Mission).
Total coincidence but I put a bid on this 2 days ago. I've played it briefly through emulation and it seemed like it was trying to be flashback but a bit more 'arcadey'. So basically what phediuk said! Find out for myself more so in a couple of days if I win!
