Marketed to hell? What? All they did were release some gameplay trailers, some website splashings here and there, and I saw a whooping one kiosk for it at every gamestop I went too. FFX got the same treatment. I never saw one commercial for LR or one magazine ad for it lol.
edit: what series are we talking about? Did you miss the news that FFXIV now has 2 million subscribers....? If you mean 13, well, that is a clear sign of series fatigue.
Dude, Before LR release, there were tons of gameplay trailers, a whole behind the scene documentary, a old school retro trailer, a live action commercial, gameplay info coming almost every week, Nomura's Art Contest and potentially more stuff that i might have missed on it. SE did their best to shove that game everywhere. Compared to LR, X|X-2 HD didn't really get properly marketing until after LR was released. Heck, i am sure they delayed X|X-2 HD to give more spotlight to LR, since it was supposed to release in Feb before X|X-2 HD. They did this despite the original game already having the english localization, which we saw in the form of a simple CFW hack on the Jap Ver for PS3.
As for the "series" remark, I was talking solely about XIII as a series.
