They have invested a lot in their in house RE Engine, which proved itself to be really efficient.

Even if you decide for a dock, there are much cheaper alternatives. The only thing in favour of the official dock is that the deck can stand on it, but I think there are also third party products available that support it.

Honestly depends how well the game is optimized. Playing Elden Ring and Armored Core without any problems.

After my full time job I am pretty much too exhausted to sit on my desk or infromt the TV and play the PS5. Playing the steam deck on the bed is a life saver.

Do you have frustration tolerance? Then go for Dark Souls, game has an amazing dark fantasy medieval artstyle and obviously hard gameplay. Else go for FF.

If you like Ace Attorney then you should not miss out on Ghost Trick. The games are from the same era and it has such an amazing story.

Ghost Trick has unbeatable story telling and is really great for a cozy couch session. Fell in love back then with it on the nintendo ds.
