There's not a vast amount one can do in 20 minutes. You could make a quick meal, watch a sitcom sans commercials, have a quick tumble in the boudoir, or you could fill out a survey and get a free game. Until the end of this month, Paradox Interactive is offering a free digital copy of Cities in Motion via GamersGate to people who complete a survey about their gaming habits. The survey is being conducted by students from Linkoping University as part of their thesis.

It's a pretty good deal, seeing as that Cities in Motion is a decent transport/economic simulator. For those of you with mercenary minds, that's a £15 game for free. I can think of worse ways of spending 20 minutes, although I like the sound of the tumble in bed. Sadly, Paradox is not offering sexual favors. Game codes will be sent out to all participants a few weeks after the end of the month.
