I'll add Viridi (succulent growing game) to this list. I think Desert Golfing is pretty much the gold standard Ur-text here.
I'm growing to think of these games like breathing meditations. You focus on them like you focus on your breath. The game is just THERE for you to play.
I'm into making more "guided meditation" games (for compassion or lovingkindness or gratitude for example). Probably a blog post on these thoughts / differences coming soon :-)
Also "Sound Self" would be like... a gong bath? I haven't played it though tbh 😁
