Well here's what nintendo life said when it first came out but keep in mind that storage prices have gone up considerably since then thanks to LLM market manipulation 🤷 www.nintendolife.com/guides/best-...

As long as they're microSD express cards they'll work fine, doesn't need to be the Nintendo branded ones. However, the switch 2 has 256 GB of storage so I haven't even bothered buying expanded storage for mine yet, nintendo games don't tend to take up much space

Five-year-old me: Oooh, that Batman cartoon! What adventures will he go on today?

*the villain is left in tears, unable to process their fears and obsessions. And Batman, a looming presence born of the inability to rationalize terror, is the only one there to comfort them*

Me: Oh. Huh.
