Oh, so you wouldn't be able to claim another Pokemon or item if you decided to go after an item? If that's the case, we may need to really adjust the "prices" of each item according to certain factors.

Or maybe it could be simultaneously with the Pokemon you're raising? Like, you can only raise 1 Pokemon at a time and save up for 1 item at a time? Or do you guys think that would be unnecessarily confusing?
