Should i buy a switch 2,

The price for the switch 2 games are expensive as hell. I hate rhe prices and decided to not buy it on launch due to lack of games im interested in, and the price. With mario tennis fever coming out im reslly tempted to buy it. I played the demo with my sister and we had so much fun with it. I would have bought it hands down i just dont want to support nintendo. 70$ usd if so much for a mario sports game. The price isnt a concern for me, my dad keeps asking me if i want a switch 2. Its the concept of 80$ usd games! I also really hate the game key cards. Pokepia also looks fun too, but its a game key card and after legends ZA im iffy on it. ( i have t seen the trailers so i cant say). Im just unsure if i should, i feel kinda guilty supporting nintendo.
