If you happen to be Genesis Knight from the Sega 16 forums, you might remember back when Beggar Prince first came out for the Genesis. It was pretty cool to get a new game at a time when that wasn't yet common, but you may recall there was a lot of bellyaching about how the cases, carts, etc weren't really that close to the original Sega carts and had more in common with Aliexpress bootlegs, likely using the same production facilities. I fully expect something like that to happen here.
Someone will complain that the plastics aren't the same, the translucency or texture of the case isn't the same, the cart is lighter than the originals, something like that. Me, I'm happy to get a Garou cart for $90. And of course some corksniffers will be "well they aren't real Neo Geo carts" regardless.
And this is all assuming there isn't some minor hardware flaw. And there always is.
