Dude, he wasn't anywhere near the truth when he came out with his 'Valve is going for Linux' thing. It was just a coincidence that, many years later, they decided to do it.
A news site isn't there for 'sparking community discussions about things that may happen in 2 years'. It's there for delivering actual news. For example that the company behind VendettaOnline hired someone for updating their art assets/effects and trying to find out more about what is going to happen there (aka interviewing people). Not spreading wild assumptions that may or may not be true.
But well, after all it's his site, not mine.
If his "source at valve" told him its coming but neglected to get the timescale right, its not a coincidence, just premature. Micheals quality of article is atrocious, and his "I'm doing it for the money posts" has resulted in me enabling adblock, but he probably did know. He just rans a rumour / conjecture site, as opposed to a journalistic site.
Average finish time less than 7h? For a full length game?
No. It's only additional episode for HL2. I finished Half Life 2 ("full length game") after 15h, Episode 1 after 4h, and Episode 2 after 5h. BTW Valve dropped episodic model. Edit: So I have to wait for 2080 "full length" H-L3 instead for 2008 Episode 3
True, I measure by bang per buck, or ((playtime / $) * quality).
I've never played anything Valve, so I didn't know that was an episode for 19.99$. By how long they took to make it I just assumed it had to be a full-length one.
Typically Valve games are cheaper, part of bundles and are frequently on sale. They also have some of the most well known, highest rated and most played games in the market. Course, they keep most of their profits and use the games to tie you into a steam account, but its difficult to complain about the games / prices themselves.
For the record though, valve previously gave portal away for free (and probably still do unless you've got an Intel graphics card), currently give Team Fortress 2 away for free, claim to be giving away DOTA2 for free, and, I suspect, will give L4D away for free for too (as its the linux lauch title, and not super new). When steam comes to linux (and the games get ported) theres almost no excuse for not trying them unless you really hate first person games (which dota2 isnt). They're all relativly modern, and 90%+ games.
