Once upon a time I thought EA localised their cartridges like they did their covers, but it seems not - regardless of where you live in the world, the square-type EA cartridges for the Mega Drive read "for play on the Sega™ Genesis™ System" (though the more exotic ones mention Mega Drive too). Also without looking too deeply into it, I'm guessing all EA cartridges are region free.
I don't think there's much point in trying to group EA cartridge scans by region if every region got the same stuff, but I'm not sure what the best way to handle this situation is. A "Mega Drive World cartridge scans" category? "multi-region catridge scans"? Accolade's unlicensed games probably do this too.
unless of course you can spot the differences. And yes, for later games EU carts do have ESRB stickers -Black Squirrel 06:50, 26 July 2012 (CDT)
