This really is good enough to deserve a thread to call its own.
Pokémon UNITE is a free-to-play, multiplayer online battle arena video game on the Switch that will also be coming to mobile. It's simple enough that you can easily get into it without every having played a MOBA before and, being both free and starring Pokemon, probably has loads of kids playing it - We all like beating children at videogames, right?
Here's a run through of some key stuff.
Anyway, it's well worth a punt given it is totally free and games are only 10 minutes each.
