Hmm... A lot of the titles you mentioned were mediocre, by todays standards. Not bad in any way (except lair), that's not what I mean, just not really that much above the rest. Is it not ok to question them then? And even more to the point, why is it bad to question games? It's not bashing when you are not sure whether or not something is going to hold up to the standard set by others.
I don't know about you, but when I'm gaming and am interrupted by an installation process and then a really long cutscene, it makes me throw away the controller in disgust and never pick up the game again.
Also, I have heard nothing but good about Little Big Planet. From the first video it has been looking like an amazing game. The only critisism I can think of for it is that it isn't released yet.
The reviews I have read about Haze gave it subpar scores, and given it the outlook of a great game in previews. Maybe we've been reading different magazines/articles.
I am sorry if you feel that Sony games are being treated unfairly, but it's not something I can do anything about or even agree with you on.
