When I was at university I made significant money participating in Game Theory experiments. The money had to be significant for impoverished students. The way our college system worked (UoY, UK) meant my dorm (I’m bilingual) room was next to the main office with the sign-up form on the door.<br><br>That was back when we had to use pens and paper, and computer graphics mainly looked like they still do in sci-fi movies!
