I love that description on the Black Mesa page, just 'Relive Half-Life.', lol.
It really was a spectacular, groundbreaking game. I used to be mad about the HL3 situation but it's been that long I just got over it. It's interesting to read the comments in this thread about what it's like at Valve, though, it explains a lot. I have often wondered how they're spending, or not spending, the endless cash they must print.
Somewhat related, I really don't like the new Steam UI. It's laggier in the way that modern software built upon too many layers of abstraction often feels like. I'm disappointed that Valve of all companies seems to have gone down that route as one use of their resources...
