@mathmom - It is great to hear that your son is doing well !
As it turns out, Tufts has a club called “The Strategic Gaming Society” with 135 subscribers on their list serve. I have seen a group of them playing board games in the student center on a couple of visits…

It is one of three university gaming societies (Tufts, MIT, GWU) listed by this international gaming blog.

Your son might be interested in knowing that a gaming cafe recently (2016) opened up in Teele Square (a stones throw from Tufts).

I believe that the Gaming Society tends to draw more from Tufts’ STEM community than Tufts’ IR/Poly Sci community.
