Pokemon Showdown seems like something Nintendo would strike down with the force of a thousand suns. Nintendo has always been against emulators, and this is very similar to an emulator. Not only that, but it probably takes away a lot of players from the Pokemon games. And yet, it has been up for over 12 years without any issue. Is this because Nintendo does not want to chase away its competitive player base? Is it because it acts as free advertisement for the Pokemon games? Is it because they don't want the backlash shutting it down would cause? Or is Nintendo just unaware of the existence of Pokemon Showdown, and it is only a matter of time before they discover it and shut it down?
