Wow, it's like they were giving you a reason to go back and explore!I gave up trying to explain this to people when I was bitching about the exploration in Xenoblade. All there was to find in that empty world was (more) EXP for discovering landmarks, bosses you couldn't kill until later on with the shitty battle system, and minerals that were only useful later in the game when they actually had more of an effect.
Also it wasn't empty, the whole point of exploring wasn't to find some super weapon, it was to find a little secret, or a nice viewpoint. The landmarks weren't useless, because it made it less tedious to journey around in the world, especially with all the sidequests which would have been awful otherwise.
The battle system was actually pretty awesome and about as PC oriented as you can get on the wii, so props for that.
And you can beat some of the bosses at a lower level, if you're good at the game.
