We know he has the money, we know he's scammed hundred of thousands out of his fans and tinybuild. We know he still lives at home and never leaves his parents' house which means he doesn't have to pay for shit and if he does his expenses are way lower than those of a normal adult. The thing is that he won't accept that, he keeps telling everyone he's extremely poor and he doesn't even have money for himself, truth is he spends it all on dumb shit like his sex dolls and a second animal crossing town. IIRC he's mentioned he glambles online too. Even if the crowdfunding campaign is successful he might pocket most of it and get some young programmers so he can underpay them.
Also... Groundwork? lol did you forget he said all the coding he's done in the past 6 years will be scrapped? Basically the actual game is 0% done. This "demo" is nothing but an amalgamation of shitty placeholders, from the code to the models, it's all a "placeholder". Nothing but a cashgrab.
