3. Remember the Potato Sack? GlaDOS is apparently drawing "power" from computers playing games in the potato sack. For every collective 48 hours for one particular game, that game's "power bar" goes up by 1%. And Steam needs to record you actually playing the game - just leaving something idling in the background does not contribute.
4. The potatoes we all frantically collected can still be collected - in fact, you are a major contributor if you even collect one potato in one game. Potatoes multiply that game's particular power, so if, say, you gathered 5 potatoes in Audiosurf and one in Bit.TRIP BEAT, you'd be multiplying EVERYONE's efforts in Audiosurf by 6x and BIT.TRIP BEAT by 2x.
J'ai un peu la flemme de traduire, mais en gros:
-Juste laisser le jeu tourner sans y jouer ne marchera pas
-48H de jeu = 1%
-Chaque patate caché trouvée dans un jeu multiplie la vitesse de remplissage de la bar pour ce jeu, par exemple si une personne trouve 6 patates dans Audiosurf, l'effort de tout le monde est multiplié par 6.
