I'm actually shocked they got FF7 rebirth to a playable state on the deck.
Obviously its the worst way to play the game UNLESS you really like portable gaming but I feel like of all the recent AAA games this one actually is legitimately is playable if you can stomach the compromises.
Somehow maintains a mostly stable 30fps experience in the world and only dipping to mid twenties in towns while not having the switch vaseline look is pretty cool.
That said it does have huge compromises huge pop in and low res being the biggest offenders but if you can stomach that its decent on the deck.
I'd advice getting it on a pc or ps5 but if you like portable gaming or only have a steam deck there are far worse ports.
