My favourite games of all time are:

Monkey Island 2 - LeChuck’s Revenge
The Secret of Monkey Island
Indiana Jones and the Fate of Atlantis

They are all well over 30 years old now but I have them on Steam on my Mac and by boy’s laptop.

Over the lockdown these (especially Indiana Jones) and also Thimbleweed Park taught him to read. Or at least they seem to have helped him very much with the breakthrough.
