Nintendo Achievement awards

[Pokemondothon]

Though I would prefer it if Achievements came with unlockable extras, like the checklists in Kirby's Air Ride. Not all of them would have to, as KAR only had a handful of Achievements with unlockables but at least even the non-prize ones built up to a larger prize in the end.

I totally agree with that. I absolutely love the way Masahiro Sakurai integrates the concept of achievements into games like Kirby's Air Ride, Super Smash Bros., Kid Icarus Uprising, etc., where you're given a blank board to start with, and as objectives are met, they reveal hints for adjacent tasks... and where some (or all) of the "achievements" also yield unlockables.
