I played the demo for the first Project X Zone, it was interesting, I always meant to pick it up. The fact that it had .hack characters was what interested me. I loved Xenoblade Chronicles as well, so wow. I didn't realize the sequel had Yakuza characters in it. The first Yakuza I played was 3, and I've been an avid fan since then (I dropped 80 bucks on Yakuza 2 when it came down to being the only one I was missing).
But yeah, I know KH has a bigger fan base and will do well regardless, I guess I was just in a funk about it because I've always been able to grab the new KHs. But oh well, life goes go on, I'm fortunate to be able to buy either of them.
