I'm surprised that people are so angry that this isn't a Fallout 4 announcement. For one, everybody knows that there's going to be another Fallout game. It's an inevitability given the success of the last two games. Secondly, it's hard to get excited about another Bethesda Fallout when Obsidian's Fallout was so much better. If Bethesda announced that Obsidian was going to make the next Fallout, that would be a good reason to get excited.
If this man knows how to write horror, he has yet to show it in my book.
"Write" survival horror? Surely you mean "design" survival horror. This is a game we're talking about, not a book or film. Survival horror doesn't need good writing. It just needs good atmosphere and the ability to make players feel vulnerable and uneasy. Gameplay first, writing second.
