Not quite right there, Razor.
Gabe realizes that the power of Half Life is in the brand name. You don't soil the brand name at the sake of more cash.
Half Life for the Mac was a product not up to their standards. They couldn't get it right, so the canned it rather than release a cash cow. Sure, they've released hundreds of variations of Half Life, but at least each variation was a quality product.
It's a lesson car manufacturers could learn from, we'd stop getting half-assed cheap Mercedes hatchbacks and 1 series BMWs, and Chevy would stop selling Geos and Daewoo's under it's name.
Incidentally, it's also why I think TF2, or whatever the product currently is, will be free with HL2. I can't see Valve watering down their products for more money. Instead of selling 8 million each of HL2 and TF2 and having people complain about being fleeced with two products, I think Valve would just be happy selling 12 million of the combination. Numbers chosen from my ass, but I honestly believe Valve would rather have one unstoppable, fully viable, all-inclusive package than sell two products for the same price that just didn't feel whole.
That philosophy bit Epic in the ass bigtime.
