Maybe the "worst" was a bit exaggerated, for multiplayer it's no doubt a great machine, but for single player the library is definitely not the best IMO. Great first party titles are a given on a Nintendo console, they always deliver that, but apart from that good releases were very rare. From the top of my head I can name Cube games like Resident Evil, RE4, Eternal Darkness, Tales of Symphonia, Skies of Arcadia, Baten Kaitos 1 & 2, F-Zero GX, Pikmin, Metal Gear :Twin Snakes, Viewtiful Joe, Soul Calibur II, Wave Race, the two Prime Games, Paper Mario, Phantasy Star Online, Ikaruga, etc and there are probably more that I can't remember now. I have a hard time coming up with such a list for the Wii.
