Lmao what a dumb faggot, just make a MAME cabinet. All the arcade games you want in one machine. Literally all you need is a screen, the housing, some generic buttons and sticks, a Raspberry Pi and a hard drive. That would cost less than even one of those cabinets, would work as well as any of them, and most importantly would be in one convenient package that would make this room less of a cramped hellscape.
Of course that implies two things. One is that this idiot would be able to put all of that together even with a guide, which (given his ability to budget lmao) is obviously far beyond his mental capabilities. The second is that this retard actually likes to play arcade games at all. I bet those machines get played once a month for like 10 minutes before he gets bored and starts scrolling on Reddit again.
