Yeah, I'm still pretty mad about the 3DS's region locking. I was kind of hoping they'd secretly take the region lock off the Pokémon games like they did with the North American versions of Black and White (which were originally region locked on the DSi/XL) and that it would slowly open the floodgates for more games to do the same but... they didn't.
I can understand region locking the eShop and if that were all, I'd be okay with it, but I hate the fact that everything is region-locked. I would easily own about three times the number of games if my 3DS weren't so restricted. I have a Japanese one because playing imports is more important to me than playing localized games but I can't afford to import every game and some games I just prefer to play in English. If it worked like almost all of Nintendo's other handhelds, I'd be able to buy whatever games I wanted from wherever I wanted and it would work just fine. But that's not the case and it's really frustrating. It's especially annoying because I've yet to hear a good explanation for the region-lock—the only one I've really seen is "oh, we want to be able to restrict games based on their individual ratings in different regions". Aaand I'm sorry but that's a really dumb reason.
I also hate that I will probably eventually end up buying another 3DS in the North American region just so I CAN finally play all the games I want to. I don't want to give Nintendo money to support this practise but I likely will anyway because I have no other choice if I want to play these games and I have very little willpower when it comes to buying (or rather, not buying) games. :(
