@bolded: I'm sure it will most probably reflect what a lot of nintendo only fans are saying right now. Should go to show that there IS an appeal in such a system being in place. There are communities built around them as well. THis is such a simple thing to impliment...add an option to hide notification pop ups and it would have served ALL sides.

It's a good idea but I don't think Acievements must be implemented (Universally) for it to not be a "lost cause."
