Speaking of Picross.
I'm kind of amazed that after all this time, despite getting all 8 Picross e games, Twilight Princess Picross, Pokemon Picross, Picross 3D 2, AND just recently Sanrio Picross, we STILL haven't gotten Club Nintendo Picross nor its sequel. You could easily offer it as a double pack at this point, or make it a reward for My Nintendo & rename it to My Nintendo Picross.
Yeah, time is ticking for those to make it over as the 3DS is fading, but I'm not expecting them to, sadly. They could've easily offered them as worldwide Club Nintendo rewards years back when the service was active, would've been a cheap and easy localization I'm sure. Oh well. :/
Interesting random observation from looking at GameFAQs' Jupiter page: Not counting Picross S/S2 and collaborations with other developers, you have to go all the way back to the freaking Super Nintendo to find the dev's only other games released on a home console. That's nuts.
