Nice review as always. I'm currently on world 2 and I'm still surprised on how well this crossover works. About the weapon issue you mentioned, as far as I can tell weapons are divides in "tiers", each one more expensive than the previous one. The difference seems to be the elemental damage. I feel that the game forces you to choose which elemental damage do you want to play with. I know that it's a low point if you want to collect every weapon, but my questions are... Does this count on the completion rate? And is it possible to have at least one weapon for each tier with every character without a lot of grinding? Also, I find the game more challenging than expected, how about the challenges' difficulty?
