Ok, so it's been a month since I last posted, so I suppose I'll give an update.
Yes, I got my copy of Soul Silver, about two weeks ago. I'm sitting at about 32 hours in (this is purely free time that I've had that hasn't been studying for my 8 exams in the last 5 weeks I've had, work, or spending time with the GF) and all I've done is complete the main story.
I've acquired all 16 badges and have a pretty decent team, but unfortunately, I need to grind quite a bit since after you beat Garry Oak at Giovanni's old gym, the Elite 4 all raise their levels, with the lowest being 58 from the first guy. The game has completely taken me back to when I first played silver in Fall of 1999; easily still the best Pokemon generation out there.
The only legendary I've caught so far is Lugia. I plan on tackling some of the other this week (namely Mewtwo & the Legendary Dogs). The Pokewalker (Pedometer that's included with the game) is an interesting concept and I've been messing around with it quite a bit. As you walk, it counts your steps & then also gives you Watts. These Watts can be used to pick up items & to encounter Pokemon on the Pedometer. The special Wi-Fi PokeWalker course that is available in Japan right now is Yellow Forrest, which only contains Pikachu. The catch is, that some of the Pikachu in the forrest know fly or surf, but these are incredibly hard to come by, I've caught almost a box full of Pikachu and haven't encountered one.
You can store up to 6 Pokemon on the Pedometer, and they get 1 experience point for every step you take. The only catch is that they can only level up once per day. The step counter resets at 12 Midnight every night, and the Watts stay on the Pedometer until you sync it with your game, to which the Watts get transported to the cartridge and added up. When you hit certain milestones with the amount of Watts you've saved, it unlocks new PokeWalker courses for you to travel to.
That's been about it so far, I'm just now getting to the metagame since I've completed all the gyms and whatnot. If anyone has any questions about the game/post game stuff, post in this thread and I'll try to answer to the best of my ability.
