His actual message, though, is spot-on: Japanese games largely do suck. Is that a generality? Sure, but other than the occasional Nintendo game or Sony game, the generality pretty much sticks.
Half of this thread still has not been able to realize that they're own dislike of Japanese games does not mean they "largely do suck." Disliking the majority of Japanese games doesn't mean they're garbage, it means they didn't interest you.
