Source has been stretched a bit far, I think. L4D is not a particularly good looking game, though they did do an *exceptionally* good job on the player models. They look fantastic and have tons of detail. I don't think the rest holds up very well. I mean, I'm not a graphics whore and I don't care at all because the game is fun, but a company without as many braindead zombie fanboys wouldn't be selling so many units on that kind of tech.
I continue to disagree that Valve makes more polished games. I've made my points about what I think constitutes a good game before, so I won't go back into why I think HL2 is nowhere near as good as advertised. But again, I'm talking in technical terms here, and the Source engine is not a bastion of stability or range. I've had plenty of problems with it over the years, particularly when you couple the fucker with Steam, which is also mechanically broken. And yes, L4D's server problems are both persistent and widely acknowledged, at least last I checked (which wasn't long ago, and there has been no significant update that I'm aware of). In my eyes, L4D had more problems than Demigod, and Valve can't even give you a reason, where Stardock could tell you why and how. Valve just refuses to acknowledge issues and won't fix anything when it breaks (which is why Steam is still completely broken for many users, like myself and idol).
Anyway, I don't dislike Valve for no reason. I don't walk around the world trying to find things to piss me off. I don't think they make bad games, whatever my preferences might be, and even if I think a game doesn't live up to the hype, that doesn't mean I don't think it's pretty great on the whole. However, I hate them as a company. I don't think they treat customers well, I think they talk a lot of shit that they can't back up, and I think they're utterly inept in certain areas and will never admit to the problems that causes. If they went under I'd be tempted to throw a party, even though it would be a terrible thing for the PC games industry because of Steam's popularity. I'd still be tempted.
