Until the end of this Thursday (Steam time) Psychonauts is on sale for a piddling one pound. A quid, or squid if you like. One buck. 100 tiny shiny digital pennies. (Or $2, or I believe 2 Euros but don't quote me. Either way, it's practically nothing). You now have no excuse for denying yourself the joy, hilarity and vision of Tim Schafer and Double Fine's finest game.
I don't have time to convince you, just buy it already, please. As a present to yourself. Go ahead, make your day, punk! - Toodles!
