Why he does it:
I don't know the guy, but I've seen this kind of behavior before, most famously from ChrisR and Crazy Dion of Neo Geo Freak USA.
When you love something so much (PCE and Neo being the two coolest systems of all time) there is a certain part of many fans that makes them want to be in on the action. They want to be part of it. They want some of that awesomeness to somehow rub off on them. This kind of shit happens all the time in many scenes in many weird and f*cked up ways, but with Tobias and NGF it resulted in them pretending to be publishers of shit when in fact they just took some existing shit, f*cked it up, and sold it as their own. Obviously NGF wanted to be SNK, Tobias wants to be...Working Designs, aparently. WDs contrived tat being the closest to a gilded coin and cardboard that is way way too glossy.
The way he refered to certain games as "requested" makes him seem like...awesome and popular. He can't actually make anything himself that would honestly earn praise, so he's trying to sell other people's awesome shit and get on that bandwagon. That's why he's not selling pirate Avatar Blurays at the pub for $1, there is no hype to vampire off of. He needs to feel like he's a part of the creation.
And it works. Personally, I'll collect anything I feel like, but any PCE game that was not manufactured with the approval of Hudson back in the day will never be real*, and since that door is long closed, I'll not be buying any "new release" or "special edition" PCE stuff from him or anyone. However, younger generations have no respect for "legitimate authority". A genuine game and a bootleg are the same thing to them, games. This is why he'll have customers. That guilder coin just BLOWS PEOPLE'S MINDS, but to me its and terrific as Sparky's carbon fibber fuel filler flap. **
And he will have his defenders, I'm sure, forever. People still defend NGF, astoundingly, usually people that are even more mentally ill than NGF are.
