I just ordered Xenoblade Chronicles for the Wii. I hear it's the best RPG on the system, period, and one of the best RPG's this generation, period. I watched some gameplay, it looks solid as hell. The graphics for Wii standards are pretty good, not that this is overly important anyways.
I hear it takes roughly 60-70 hours to rush through the story the first time, but if you take your time and want to complete the side quests and item hunt, explore the worlds, etc, it takes 150+ hours, so there's a shit ton of content here, and as an avid RPG guy, I will definitely be doing all the content.
I can't wait to get my hands on it, yummy.
