I don't think that Nintendo has been stale, personally. Tastes are going to differ, of course, but Pokemon Legends: Arceus was a great start to the year for me. If you haven't played it, I recommend it (I gave it an 8 on this site). I also really enjoyed Kirby and I've been enjoying Xenoblade 3 so far (stay tuned for the review!).
BotW 2 missing 2022 definitely felt like a loss, but with Pokemon Legends: Arceus, Kirby: The Forgotten Land, Switch Sports, Mario Strikers, Fire Emblem Three Hopes, Xenoblade 3, Splatoon 3, Mario + Rabbids 2, Pokemon S/V, and Bayonetta 3 all releasing in one year, I think that it's still quite a good year.
I honestly feel like people don't appreciate how much Nintendo does put out. In 2019, 2021, and 2022 Nintendo has put out more than Sony and MS combined. Not saying Nintendo is "better" of course because tastes are so different, but I feel that has to be respected.
