I wish you could add these games to your shelf in the Genesis classics game. It's weird to have that and then have all these games seperate on your switch menu.
Also; some of these games were included in the PC version of Genesis Classics, so it very much so feels like we are being nickel and dimed here... Oh well at least they are available to play for those that really want to see them on a modern system.
Different developers, different contracts, different products. The Classics collection is a bunch of ROMs in an emulator frontend, like they did on PC years ago. The AGES presentations are torn apart and put back together with new features and a terrific attention to detail that justifies paying eight bucks each for them.
I'm OK with them in the different formats because they serve different purposes. And I, SEGA whale that I am, buy them all. Including the SEGA Forever collection on mobile.
