Probably not. In case you don't know the joke behind this, there's a bootleg Mario game called 7 GRAND DAD, which has become pretty well known thanks to Vinesauce Joel. However, this is only a recreation of the title screen.
But that doesn't mean I don't want somebody to make a Grand Dad game. And I'm not talking about romhacks like Grand Dad Bros. or Grand Dad the 13th either
Yup, that's the one. I hope I'm not the only one that wants to see a Grand Dad game though. Music made from the midi converter, dialog full of mistranslations, and topped off with a nice LGN logo (this is supposed to be a "bootleg" after all). It would be a perfect storm of TRASH and GARBAGE!
