There hasn't been a new Art Style game on WiiWare since October 2008 -- they've all gone to DSiWare since that platform launched. Today, the series returns to Wii, in much the same way as it started: with a fancy update to a GBA Bit Generations game. It's accompanied by a compelling, odd-looking game from NIS America.
Meanwhile, DSiWare has poker, a vertical shmup, a puzzle game about racing, and a hidden object game about historical crime. See all the new downloads after the break.
