They are however now offering 50 stars per downloaded title for these systems! The majority of software is eligible, including eShop exclusive titles, and free downloads such as Pokédex 3D, Nintendo Video, Nintendo Letter Box, Wii Street U and promotions like 3D Classics Excitebike/Kid Icarus.
Virtual Console titles do not appear eligible for reward stars however.
Hop onto your region's Nintendo website, log into your Club Nintendo account and see how many extra reward stars you can redeem with those pesky surveys. I redeemed 1350 stars in total today, 400 of which were from free downloads alone!
