No, it's not a scam, yes, it's real, yes there's proof, yes I'm going to tell you how to do it.
I'm a regular person, with a regular life, just like you. You don't have to be 'special' in any way to do this! Your mother could even do this! Honestly, there's nothing to it. I'm not doing to post 4 pages worth of information, trying to sell you this. I'll just say it works, but you need to stick at it. I don't know how many are left to give out, so I'd suggest doing this ASAP. If you don't have a Nintendo Wii just now, then you have nothing to lose, so here's how to get it;
1. Register at this website
2. Complete an offer
3. Refer others to do the same
4. Recieve your FREE Nintendo Wii!
That's it. It's easy! All the instructions are on the website. I really can't make this any more easier for you. :) Good luck.
