I'll just join in 2011, once Covenant of the Plume is $20, brand-new.
No doubt they'll regulate the number of points you get by how much the game actually costs.
That might go against them, seeing how I can just buy a brand-new copy of Magical Starsign or EBA for $20, brand-new, at my local Play n Trade, while getting the same amount of points (30 points per brand-new eligible DS game for Club Nintendo).
