I own Pearl, brother owns Diamond. Unless it becomes cheap, and I sudden complete Pearl. I'll get it, otherwise no. Knowing my brother, though, at some point within the month (or next) it'll turn up at the house.
Right, i've only just got the first gym badge but i've found the game really quite addictive. Probably no surprise there. Very enjoyable though. Only thing i found myself annoyed with was that i got the game with my student discount at GAME, but went into Tesco a minute ago and saw it for 25 quid, which was still cheaper than what i got it for. Still...game points..won't complain.
