Want to try and push ahead the release of Portal 2? Just open up Steam and start playing one of the games available in Steam’s Potato Sack deal! Or, alternatively like me, just start one up, minimise, and continue your regular scheduled programming.
Essentially the game Valve is playing here seems to be:
1) Spend time on selected game
2) ??? (Well.. the bar here fills up)
Who knows, it might not be able to be done, but it’s certainly a challenge! And isn’t that what Portal is all about?
