I'm going to Japan later in the year and am trying to decide what gaming system I should take. I am considering all factors - battery life, weight, size, library, etc. Due to the premium on weight and space, I only want to take 1 gaming device. I have access to basically any portable gaming device.
My current frontrunners are
Steamdeck - Huge library, but also huge device.
Hacked 3ds - Huge library, not the best battery life
Nintendo Switch - Requires cartridges, joycons suck but better controllers take up more space and require a different case.
Anbernic handheld - Huge library, but not many games I want to play for long stretches.
Nintendo DS with a flash cart and a GBA everdrive
Playdate - lol just kidding
What are your opinions on the best portable device for such a journey?
