The pointlessness annoys me. It looks like we might get it a day early at most, for which countless thousands of people would have to spend the preceding three days constantly playing games they may not particularly want to play.
Surely it makes far more sense to just play/do anything you want, as usual. If you want to play one of those 13 games, go ahead, otherwise do something you'd prefer. It's a win/win scenario.
I reckon this end-game is Valve giving back to the indie devs for promoting P2 by ensuring that thousands of people feel obliged to buy and play their games. This, to me, explains the minor effect the playtime's had so far: there's like one hour off the clock, almost. I expect that this part is designed to last at least three days so that the indie guys get their effort's worth out of it, while Valve also get to say that they released a game slightly earlier than they said they would.
It's obvious of course, I just don't understand why most feedback seems to be positive. It is clever, but still...
"We COULD release it on the 15th, but you can't have it until you've played Toki Tori for 24 hours."
"What? Why? Oh, I see, you owe someone a favour. I'll just get to work then, will I?"
"Please. Oh, and you should also spend most of your weekend searching for obscure potatoes, for no clear reason."
I hate potatoes. They're dry and brown and horrible. And don't worry about GLaDOS, she's booting up either way. I've been watching videos of it happening for the past nine months.
Enjoy your weekend.
