Before I joined PC, I enjoyed my Diamond game but hadn't finished it - in fact, I'd only got as far as the first gym! I restarted and finished it - then I started trading, and I've met so many awesome people and done some great trades and deals, it's made the whole Pokémon experience more engaging and entertaining. I hope that Wi-Fi is something Nintendo keeps hold of, and it doesn't drop out of any future pokemon games *not that I think it will*.
