Most disappointing game you've ever owned?

[milkyjoe]

So many Gamecube games to choose from... Mario Sunshine, Double Dash, Wind Waker, Starfox Adventures, Eternal Darkness, etc, etc, etc.

I'd be tempted to say Nintendo's entire GC output apart from Metroid Prime and maybe Melee.

As for this generation, LA Noire stands out above all other contenders.
