Wojtas, Socom 1 sold over 3.5 million, Socom 2 was higher, but I cant' find the exact number here on VG chartz for 2, 3 and CA. It's one of Sony's strong titles that always sells quite well and I'd expect Socom Confrontation to sell very well too. There were many who were utterly addicted to the online in those games (Not so much for 3 and CA which fans bought but stopped playing after not very long).
My pokemon brings all the nerds to the yard. And they're like, "You wanna trade cards?" Damn right, I wanna trade cards. I'll trade this, but not my charizard.
