If Jonesy got into Smash I'd be totally cool with it. I played the game mid 2019, had fun with it, and set it down when I got bored. But the game itself is oozing with charm, and it has a large playerbase for a reason-it's free, it's fun, it's addicting, it's easy to play and tough to master, and it's constantly being updated so that returning players stay entertained. If they get in Smash not only will I be happy for the younger crowd who can have a character they can immediately recognize, but also in terms of gameplay because having a character that can build pre-made structures and has projectiles sounds really fun to play as and against, in both casual and competitive environments.
