Pokémon B/W. How's the adventure going so far?

[Chutzpar]

Black City and White Forest empty out if you don't beat the Elite Four within 10 days of starting your game, I believe. You have to use Entralink with someone, find the NPCs in their game, and invite them to populate the Black City or White Forest for you.

I found this out about 5 days after I got the game, when I hadn't even beaten Gym 3 yet. Suffice to say, by the time I get to the White Forest it's going to be DEAD :c
