You misrepresented the deep dive to drive some point about 'only graphics', when it's obvious you don't know shit about the technical difficulty of turning a 25fps animation frame sync game into a physical based render that's running at 60fps while maintaining the consistency of said 25fps breakpoints. They're pricing it at 40$/€ because they know people will pay, and it's in line with their previous work pricing. Regular D2 classic b.net servers will still (as is stands right now) be up, with all the good and bad that comes with it (bots, limitations, items that avoided the rust storm, etc.).
Ironic, cause you don't know what you're talking about either.
