The game developer is basically taking all the hate that people are really directing at a society that doesn't value the same things they do anymore. I thought SNES Zelda and Final Fantasy were the best, but I didn't threaten the developers when they moved to 3d.
It's also a side-effect of being involved in the community as a creator; if you were pissed at the 3D Zelda what were you going to do, fly to Japan and track down Shigeru Miyamoto? Send him a nasty letter?
But here we have someone who posted something on his own site, and not only allowed comments, but cleary was reading them, and people just attacked him.
