Yeah, I think you might. I mean, Elin is like the greatest Xeno + FFXII fangirl ever and she liked XB a lot. But as it's been mentioned above, it has no relation whatsoever to the previous games.
It's also different from previous Xeno games in a sense that it's more like an actual game and less like a series of cutscenes. There's lots of exploration (with tons and tons of scenery porn) and free roaming/dungeon crawling with occasional story cutscenes between them, so in that regard the rhythm of the game is reminiscent of FFXII. The battle system plays a bit like FFXII, but it's actually rather different. And there's no Gambit system, which sucks.
The cutscenes themselves are pretty badass, and much like in the case of Xenogears, what starts out as a rather simple revenge story develops into something more complex by the end. It's... uh, probably not Xenogears kind of complex (which I was actually thankful for), but I thought it was a really nice story nonetheless.
I could go on, but I have a feeling you wanted a short answer.
(Overall, I think I prefer FFXII. But that's just my Matsuno fanboyism showing.)
