And before you answer, please do keep in mind that although Grim Fandango and Psychonauts have been hailed as two of the best games ever, Epic Saga -Extreme Fighter- is indeed very freeware. As in absolutely free. And you wont have to download a thing either. Besides, it features gnomes, silly humor, piss easy gameplay and is signed by the wicked people of Double Fine. Play it here.
