What size would you recommend ?

Whatever size matters. I ended up buying a 512 GB with 512gb micro SD. I have like three games that take up 100GB (Elden Ring, Witcher 3, and some other game I forget), and like fifty indie games.

What’s the battery like when running games or watching movies ?

Depends. It’s like a laptop, and depends what you’re doing.

I play Elden Ring while it’s plugged into my dock + wall outlet, so it’s on the big TV. If I played it while portable, it’ll last like 1.5 hours.

Where I can play Vampire Survivors or many 2D metroidvanias for like 4 hours.

Any gotcha moments when running a deck?

Be careful because if you’re like me, you might no longer build gaming PCs ever again.

I say that and honestly, most graphic intensive games don’t look great on Steam Deck. Like Cyberpunk looks great on a mid-level gaming PC where it looks like Lowres muddy blurs on Steam Deck. But if you never knew how it originally looked, you might not complain.

When it comes to electronics, I’ve never once gone “Man, why did I get the largest size?” :)

If you can afford it, get the 1TB OLED. It’s only $100 more.

$400 for 256
$55O for 512 - +$150 for 256GB is $0.59 per GB?
$650 for 1TB - +$100 for 512GB or $0.195 per GB. If you compare it to the base model, that’s +$250 for 744GB or $0.336 per GB.
