I actually bought PBR after playing Black and White.
I had a copy of it a while back, like 4 years ago, but it was on a jailbroken system (bad me). But that stopped working, and I couldn't play PBR anymore since the disc only worked on for jailbroken systems.
So, after months of waiting, I finally found a copy of PBR at my workplace (a Gamestop rip-off). I haven't played it a lot in the past week, but that's because I just got a 3DS. I'm busy trying to beat Pokemon Rumble Blast.
But once I finish that, I'll probably hop back on SoulSilver and train some more, so that my team on PBR will be nicer. I just beat the first round of each are; now I just need the Little Cup one (it's hard to get good lv. 5's before beating the Pokemon League once through.)
