According to Xenoblade Chronicles X director Koh Kojima on the game’s official twitter account, Xenoblade X will feature a full enemy encyclopedia. You can view 3D models of monsters you have encountered, check what drop items they have (something that, for the record, would have come in very handy for the first Xenoblade), and the like. This is something they wanted to do with the original Xenoblade Chronicles, but they didn\’t have enough development time. This time they get to add it in – and the 3DS port of Xenoblade Chronicles will include this feature, in some form or another, as well.
