Portal 2 has a very fun co-op story mode. In fact, I’d recommend the solo story mode for both Portal 1 and 2 as well. One of my favorite video game stories ever.
I haven’t played them myself but I believe both It Takes Two and A Way Out were designed to be played in co-op only so both their stories should be good.
One gift I’ve been giving out that’s pretty popular is an automatic foam soap dispenser. It’s a nice little quality of life improvement and since you add water to the soap to make it foamy, soap lasts a lot longer too.
There are a bunch on Amazon. I would find one that you like the look of and make sure it charges with USB C.
