Uh, wrong. There are a number of non-Valve games which use Source engine. I could provide examples, but I think you can do a simple search. Anyway, my point was more about creating an engine that could be updated in a modular fashion so that it doesn't need to be replaced with a completely new iteration each time it starts to get outdated.Dylalanine said:No game uses the Source Engine that's not under the Valve francise.
So did Isaac Newton, according to his own words, probably the most famous utterance of that quote, and he was one of the greatest scientific minds of all time. That's the whole point. No one ever starts from scratch, because if you did, you'd never get anything done. Everyone who's done something great has built upon the work of those who came before him. That's what Valve did with HL2, and it really was revolutionary.it stands on the shoulders of giants
Your original contention was that HL2 didn't have much impact on the gaming landscape, but I'd like to see how many games you can name that have been more influential on modern game design than Half-Life 2. There aren't very many. Honestly, I'm not sure what you're really getting at here. You even agree that HL2 is a great game, but you say it hasn't had any impact. It's had a huge impact, and you don't even need to be a fanboy to think so.
As far as DNF... well, it has its own legacy. That legacy doesn't remind one of HL2. It reminds one of Daikatana. How to disappoint gamers after years of hype. Saying that it's like HL2 due to having "the same elements in different amounts" is like saying your neighbor is like Sammy Sosa because they can both hit a baseball, they just hit the baseball a bit differently.
