Even with a steam deck, I am probably going to get the Switch2, mostly because I can lower my head on in-game profiteering, which is increasingly prevalent on steam games.
An impossibly high bar given that the Zelda games are some of the most critically acclaimed games of all time.
You can absolutely make a game to the quality of Zelda as an indie developer.
Not as enoirmouus as paying a studio in California to make a failed GaaS shooter service. But still a large step past a AA budget.
I'd say at the bare minimum you need a very solid staff of 5 to pull it off though. Hollow knight did it with a rough core of 3 devs + composer (and other support, of course). The very ambitious Toweers of towers of aghasba was reportedly 6 devs IIRC, but that's TBD and might have scaled up.
