> I've been thinking a lot about finding a genre or mechanic that would still "work", but I find it sad that I cannot get the long term enjoyment without worry anymore from games as I could years ago.

Try some games that are designed more as "cinematic" experiences. This isn't a bulletproof strategy (cinematic games can have grindy elements), but it usually works.

Some new-ish recommendations:

• Hellblade

• Gris

• Life is Strange

• Journey

• Abzú

• Monument Valley

I also feel that Nintendo in particular has done a good job of avoiding the the stuff you describe, in their mainstream titles.

Actually, another strategy would be to just avoid any game that let's you purchase in-game items or currency, regardless of context.
