I don't understand why anybody wants a 90-minute cutscene interrupting the gameplay...
I'm not saying "yay for more cutscenes in games!" but if you play games for entertainment, and a well-made cutscene entertains you, then... that's a good thing. The issue is when you can't skip them (apparently not an issue here) or they don't entertain.
or why anybody wants to install 4.6GB of data on a console to play a game that comes on what is supposed to be the best disc format ever invented...
It is the best disc format right now... it's just not as fast as a harddrive.
