I have a bunch of things on my wish list, but for this top 10 list I focused more on improvements to stuff that was already in Xenoblade Chronicles as opposed to crazy new ideas.
I have some crazy new ideas too though. The trailer seemed to suggest that specific parts of monsters can now be targeted, which leads to all kinds of potential awesomeness. Anyone remember Chrono Trigger?! Having to take out certain parts of enemies before you could attack the others? I love that kind of thing.
