GoKawiilDon’t do an April Fools’ joke. Put the time and energy into doing something productive that will materially benefit the world (or, less idealistically, your business) instead. Or just don’t do anything. Abstaining entirely would still be a net positive over the drain of resources and mental energy.
Do an April Fools’ “joke,” but actually follow through on your stunt. This is arguably not a prank since you’ve actually created a video game skin or a real product that people can buy — but it doesn’t really hurt anyone.
Do an April Fools’ joke, but be extremely clear from the start that this is a dumb joke and you have no intention of doing the thing that you are “humorously” pretending to do. Does this defeat the purpose of doing an April Fools’ joke because you’re not “fooling” anyone anymore? Absolutely. (Please see my first two points.)
