I played Xenogears for the first time last month and I was blown away. The world and story that Takahashi crafted was amazing. It amazes me to think that could have been the game we got instead of Final Fantasy VII. I was impressed by Fei and Elly's relationship, probably one of the best romances in gaming. Also was incredibly surprised when they were flat out shown to have sex with no trying to sidestep around it.

I also absolutely loved Xenoblade, and greatly enjoyed Xenoblade X, though not quite as much as the first. I am very tempted to give Xenosaga a try now, as I can firmly say I am a fan of the series. (Though I hope the next game is as story heavy as at least Xenoblade, preferably Xenogears).
