Why do I think of Colourless when I hear that?
Anyway, for an achievement list on a game targeted to 8-12 year olds... it's pretty solid. Most are things you'll do in the main story, and it'll constantly reward you on the side-stuff for more desire to do them, and there are some between "okay, seriously what the hell?" and "ah, i'll just take a minute off the main campaign then..." specifically the E4+Champion ones. Using teams with one common type is excellent and foments the idea of trying out all sorts of Pokemon for fun.
It's not a perfect achievement list, and it'd be nice if they'd get you some useful items like Xenoblade (imagine if most of the extremely easy got you a potion and getting the Get All medal got you a masterball), but it's still solid and has some fun stuff in it.
