Played Xenogears and I have this love-hate relationship with it. I loved the overall story and mythos, but at the same time the game had some needless padding that was sometimes braindead-stupid and only served to make an incredibly long game even longer. I also did no enjoy the gear battles as much as those on foot, so it was a shame the game was basically a marathon of those nearing the end.
Being European, Xenosaga was this elusive thing for me. I managed to play XSI using swap magic and I dug it. I liked spotting how it connects to Gears and overall, the story was really interesting. And then I bought II and I just couldn't being myself to beat it. I still liked tge story and characters. Funnily enough, it was the music that made me quit. I loved the Kajiura part of the soundtrack. The rest made my ears bleed.
And then came Xenoblade. I've already praised this game a lot here. Needless to say, it's one of my favorite (perhaps even no. 1) games of all time. The story, characters, world - everything works just so well together.
