Thats called piracy mate. Its theft. Move along.
I've got loads of Wii, Xbox360 and PS3 games that I bought legitimately, I'll be f**ked if I'm going to pay full price for them so some cheap schmucks can have them for free.
Where do you think the money comes from that keeps developers, developing new games?, if enough people are stealing them instead of buying them, then at some point in the future there won't be new games for you to steal.
Stick to downloading old games for systems that are no longer on sale and actually paying for current gen games.
