if i had infinite money the last thing that would come to my mind was getting a 3ds
would be too busy with blackjack and hookers...
ok maybe i would buy nintendo and end the "switch" nonsense, would buy sega, melt the 2 companies together, create the nintendo dreamcast 2
and then buy google and apple
toy with apple, like release a new apple phone every month and see who are the hard core fans that still buying their products, would continue this every month each adding something meaningless and removing some great feature (like apple did with the phone jack)
after like 10 months create the iphone NR (the iphone not rechargeable) everyone could get it in stores, would need to replace to a new battery like 3-4 times a week depending on use, would make a deal with duracell
damn, i would create the illuminati if it doesn't exist and play god.
but i wouldn't even get a n3ds.
