Generally speaking, you don't go to events like this because of the dinner menu. You go for the support/fundraising and the meet & greet.If I paid $275 for a dinner and was served Frankfurter sausages and chocolate mousse I would feel like I had been done over. That's a hilarious meal for that amount of money. If people paid that and aren't fucking raging about being ripped off then just....wow.
Games looks fabulous in many ways but the pricing practices around it seem less than healthy. I also get the impression that it's just one huge mission creep in terms of features but I'm hardly informed from a few brief gameplay demos.
Was Roberts in attendance? That'd be about the only person I can imagine a supporting wanting to shake hands with. If it was just some random developers, that'd be pretty uncool.
