Highest quality, most diversity, and best value of all the exclusive lineups. And this isn't even counting WiiWare stuff (Zombie Panic in Wonderland, Tomena Sanner, Bit.Trip Runner, lighttrax, Rotohex, NightSky, Q, Jett Rocket, Dive, Salamander ReBirth, Jackal ReBirth, WarioWare Showcase, etc, etc)
