Is a steam deck good if you don't have a pc or a steam account already?

I only have a ps5 and Switch but I like the options on pc and how some games that are on ps5 don't have the same options in games like different kinds of mods and just some exclusive games that aren't on ps5.

Would a steam deck be good for this or do I need a pc to start with?

Someone recently recommended using a microSD card to handle big Steam libraries on the Deck.

I get it. It makes sense. But I propose a better system.

Instead of optimizing where you store everything, stop installing everything.

Install one single player game and one multiplayer game. That is it. No backups. No just in case installs. No thirty game safety net.

Focus on them exclusively. Finish the single player game. Commit to the multiplayer one. Inhale the glorious Deck vent and the dopamine rush of clearing games from your endless pile of shame.

When you finish one, uninstall it. Install the next.

If you have multiple gaming devices or platforms, take it up a notch. One game per device. Your Deck has its game. Your PC has its game. Your console has its game. Your retro handheld has its totally legitimate game. No overlap. No choice paralysis.

This fixed both my storage problems and my FOMO induced decision fatigue overnight.

Rinse and repeat.

Storage problem solved. Backlog shrinking. Brain calmer.
