She had a couple old card and casino games she bought in the later 90's... they installed in WINE without any real issues at all, total surprise to me, but they were likely just using simple GDI calls or whatever, prior to DirectX really taking over. I had also installed a handful of similar games via the distro repositories.

She mostly used her browser for email (Yahoo) and to order grocery delivery once a week. She emailed and shared pictures with extended family quite a bit.

Nothing really extreme at all, and not really a heavy gamer by any means. Just casual play. Oh, she liked a few of the columns/gems type games as well.
