For those that loved playing this on console or PS Vita, getting this running on your Steam Deck isn't much hassle compared to some other (less popular?) JRPGs.
This is the Complete Edition that includes Cyber Sleuth (started on 3 different platforms - still unfinished) and Hacker's Memory (which I haven't started yet)...
For some good ol' monster collecting/breeding/fighting and turn-based battling, my experience has been great so far except for a few random crashes back to the Steam gaming desktop.
All I did was:
- Install the game as usual, but don't start it!
- Switch your Steam Deck to Desktop mode (hold the power button and select it)
- When in Desktop mode, open Steam and launch Digimon Story Cyber Sleuth: Complete Edition
- You'll go through a brief intro and you'll have to select which game you want to start (Cyber Sleuth or Hacker's Memory).
- After that, you can go through the game's menu to select the Fullscreen option (I have my resolution set to 720p).
- You can exit the game at this point and then switch back to Gaming mode
- Once you're back in Gaming mode, start the game as usual!
Overall it's been great and running fine, but I have had a few random crashes to desktop that you can defend against by saving constantly. Note - sometimes hours will go by with no problem, but sometimes it'll happen 15 minutes into a session, usually after a transition/load of some kind like leaving the DigiLab.
It's kind of a bummer to worry about that (because you will forget) but hopefully this will improve in the future.
