I support the person who puts up the money to make something they have dreamed about come true. Especially if that person was told time and time again that there was no point, that Doom 3 was not meant to be multiplayer focused.
Would it be nice if he gave away something awesome, sure. Does he have to? Hell no.
I mean you can play mcs, its got all the stuff there for you. Really this person has invested in a product that is valuable, just because its hard to make money off of it right now doesnt mean that it should be free r&d for all. Sure Id gave doom 3 source out, but that was after they made lots of money on it. We aren't entitled to someone elses hard work for nothing.
You're probably right in the sense that we are not
entitled to it, no. But it's still a backwards and selfish mentality, and ultimately, one that doesn't provide you with a single tangible benefit. Quite the contrary, you condemn the fruits of your labor to a restricted audience and a disposable, finite lifespan. Feel free to correct me if I'm wrong about this.
And, frankly, right now, MCS isn't any better. Sure, it may come with the promise that the source will be available
someday, but until it's up on Github with build instructions, it's just one of countless other mods that's entirely unavailable to people not on the Windows platform.
And to prove I'm practicing what i'm preaching -
