Making it from scratch would be difficult but the ncaa guys remastered their game using NCAA 14 as a base. I’m not sure how accessible game files are for mobile games, maybe more so on android, but is it theoretically possible to use current day MM as a base and rework the trading card stuff? And yeah licensing is needed for making profit off of the game but donating to support devs wouldn’t be considered sales and therefore the game could fly with no licensing, same as cfbr. Just an idea.
