Honestly my current jump back into gaming was playing Breath of the Wild on my Switch while on deployment. I did have a hiatus a few years back which was broken by my attempt at beating Bloodborne (wholly unsuccessful, btw, it's not really my speed but I enjoyed the heck out of it). My go-to game for decompressing is Stardew Valley. I just love being able to jump in and maybe harvest some crops, maybe explore the mines, maybe go interact with the villagers even.
Another tactic of mine when I'm in a funk is to pick up an older rpg (snes or ps1 preferred) and start working on it.
