Or... and this is just a crazy theory... but maybe they were simply happy that those games were announced?
I know I know... crazy talk
there's a difference between being happy about an announcement and then completely pooping your pants over a remake, a niche title getting a kickstarted sequel and a game that looked to be basically on its death bed for years.
I'd much prefer the people I look to for information and thoughts to be more reserved and controlled when they see something that excites them. By all means, be EXCITED, but there's no need as a grown man to cry over a video game or jump around like a monkey. If GT is really making a shift towards "personality driven content" then shouldn't their personalities have more than one personality?
