Good god, some of you guys are insane. The story in MGS4 is a pile of steaming hot garbage, but I'm not going to continue to derail the thread.
The OP's point is that, barring some statistical anomaly, the evidence suggests that, for whatever reason, Gamespot is more likely to post 10s now than it had been in the past. There could be any number of reasons for that-- perhaps staff turnover, perhaps editorial pressure, or perhaps games are just better now than they're even been (I don't agree with that if it's their opinion).
Many of you seem oddly defensive about this, which I think is silly. OP simply said that there has been a change in philosophy. He didn't say (or even imply) that the change was a bad thing. Nor did he say that any of the new 10s were undeserving (on the contrary, his position could very well be that Gamespot should have been posting more 10s in the past).
