I started back up the first Blasphemous after finally getting around to figuring out cloud saves on the steam deck (I just forced the windows build). I'd definitely like to get through it and into 2, but I feel like I'm bombarded with huge games I need to play this fall. It might work as a game I can play while watching TV. I started back up while watching 24 (I loved it when I was younger, but watching back I really didn't recognize just how great the writing was.)
I'm still hooked hard on BG3, though. A fucking lot of hours in and I'm still on act 1.
What kind of legwork are you willing to do? Do you have access to an old computer capable of being used as a server?
I have not used this and can't vouch for it, but some digging led me to ethercalc. On the surface it looks looks legitimate enough to explore further. As I always would when installing anything or using an online service with sensitive data in play, I highly encourage doing your own research to be sure that you feel comfortable that it's legitimate and safe, but I didn't notice any glaring red flags.
