The Curse of the Golden Idol was released in 2022, but could probably run on my microwave. It's a brilliant little detective game inspired by The Return of the Obra Dinn. Highly recommended.
Another detective game from 2022 I loved that's similarly untaxing on hardware was Strange Horticulture. You run a horticulture shop in a Victorian-y fantasy land where strange things are happening...
