I decided the release of the MD Mini would be a fun excuse to delve into a ton of old MD games and talk to a bunch of developers, so I own half a dozen of ’em for the sake of thoroughness.
Looking back on it, I’ve bought at least one version of all of them, just for the sake of getting a hands-on, and then flipped most of ’em pretty quickly, with the exception of the Jump FC Mini, which was too silly not to own. (I was expecting a Disney/Marvel/Star Wars equivalent for the west, and I wonder if that might still happen someday, not that I’m particularly interested in any of those games.)
Beyond that, I’ve mostly bought them as gifts for other people who won’t ever fire up an emulator or buy these games off a digital store or whatever, and they always go over well (controller cable length aside). More than anything, I’m grateful the MD Mini exists because it’s helping me take some of those awful AtGames/Jaaks Sega boxes out of circulation.
