I'm pretty convinced that marketing and hype is tied more to success than quality is, nowadays more than ever.
I like the point about Japanese companies coming up with diverse and fresh new IPs instead of relying on their traditional stable of games. Lots of the bigger companies have gotten way too conservative and risk averse. Oscar, while I agree with you big time that Japanese companies are much better at making games with a modest budget (with obvious exceptions), as a gamer I do kinda wish to see a few more crazy pie-in-the-sky risks from their developers (i.e. FF7, Shenmue).
