Well for the PS2, i support pirated games...
But Nintendo? No way. I believe most Nintendo fans would be loyal enough to buy the official games, i know i will be. When i buy an official Nintendo game i don't mind paying $99, i know the work, effort, time and quality that goes into them, wish i could say the same for some of the PS2 offerings years ago. That's not to say every Wii game is going to be great, but i can assure you Nintendo ones WILL be and worth every penny, and besides you get the nice colored manuals, unlike *cough* PS.
But i guess everyone has their own opinions, but i'm not going to mod my Wii.
