it was by mistake lol. it was kinda stupid lol. i basically thought white 2 was the sequel of pokemon black because there was Reshiram on the cover lol, so i bought that and played it. obviously i understood i got the wrong version but i didn't really care too much tbh. Anyway, several months later, i decided to buy black 2 to "make things right" lol. so, i sold white 2 and got black 2 lol. THat was my only time. I ve never owned two pokemon versions at the same time tbh, i ve always seen it as a waste of money since i m not a collector, i guess. but anyway i think it was worth playing pearl lol. gen 4 is my fav gen and i m like obsessed. indeed i plan to get at some point the japanese version of pokemon diamond and prolly platinum too. i could consider getting pearl too just for the collection, but, again, it still would feel a waste for me.
