I just shake my head everytime I see these kinds of compilations released. I’ve been playing these games for years, through emulation. These bundles advertise being able to use filters for ‘authenticity’ gameplay, online playability and such. Emulators can and have long done these things too.
But, there are people out there, who’ll wait for years on end for these compilations to be made and some shamelessly buy them. When you can cut all of that down by spending less than 2 minutes grabbing a ROM and grabbing an emulator before you’re well on your way to revisit your old favorites.
The re-releases sometimes come with improvements, such as the ability to save mid-game, or networked multiplayer, that would have been impossible with the original release, e.g. a standup arcade game.
…That you can do through emulation also.
