Ask HN: Games suggestions for hacker kids?

My friend, a self described English major type, has a son (age ~8) who has a very logical, analytical bent, as well as some subtle autistic symptoms. He struggles to know how to nurture his son's strengths. I would guess that many hackers here, like me, would relate to this kid from having similar strengths and interests at his age.

Do you have any suggestions for games and ways to engage kids like this and foster their inherent abilities and interests?
