I've completed the storyline, except for defeating Red, because I have an aversion to caves and other areas where I know I'll run into wild pokémon every five seconds (Repel! I hear you say. Well, no, because I am also too tight to spend money on repels :p).
I also haven't done any of the wi-fi events, because while they were on we were staying with my parents 'til our house was liveable, and my mum (who knows nothing about technology) was convinced that if I temporarily changed the router setting to WEP, I would delete the Internet :/ As a result I didn't get the promo Mew that was available recently, but I do still have my cheat code Mew from a few generations back (My only cheat code poké, I should point out).
I'm currently working on completing the National 'Dex through breeding, trading from my Diamond cart, and such, but it's slow work. Still, it's keeping me occupied until my partner and I receive our copies of Black and White!
