Smash bros is a really great game because it's super fun to just play casually if you don't want to get super competitive. It can be entertaining and hilarious, or it can induce monopoly-level violence, haha.

Dude, Zelda Breath of the Wild and its sequel, Tears of the Kingdom, are both really beautiful games. Nintendo spent YEARS on each game, recklessly blowing past their announced release dates, lol. But in the end no one was mad - everyone just appreciated that they took their time to really get it right. And they did. Absolutely worth the buy. There's so much freedom to explore and play through the game however you want, the map is huge, and there's an endless amount of side quests/collectibles/objectives.

I'd start with BOTW, take your time with it/enjoy all the little things about it, and then go to TOTK, which is an even bigger game.
