I got to Chapter 5 or maybe 6 last night. You'll know where I am by this picture:

I won't be able to finish until later tonight. But, wow. Some REAL twists that, although I saw most of them coming so far, have been really entertaining. Wheatley is great. Also, the gameplay is superb and the graphics got a nice bump (even though they are mostly the same).
Twisted Metal: I don't work long shifts, but my p[oint was that most normal people wouldn't be able to pull an all-nighter to play the game. I think they released it at a decent time, but based on reports from some of the ARG people that were "taken" to valve HQ for the launch, Valve had control over when the game released for the whole time glados@home was going on (which makes sense because they never told anyone how glados@home worked and could have changed the rules at any time). Anyway, the whole glados@home thing was a really bad sendoff for a really great ARG.
