May I draw your attention for the ISAGA summerschool at the end of July in..... Atlanta (GeorgiaTech)? The theme is sustainabillty. There has been quite some registrations from all over the world.
Check the website. Also find attached the leafleat.
Among many interesting speakers Dennis Meadows (famous for The Systems Thinking Playbook) and maybe Dick Duke himself. And famous gamedevelopers like Willy Kriz, Marcus Ulrich and Paola Rizzi.
There is a reduced fee (€ 500 in stead of € 600) for NASAGA members (as ISAGA affiliative) and for students there is even a greater discount.
