While Nintendo of Europe is yet to reveal any info on a European launch of the Wii Ware service (Wii Software in the UK), Japanese gamers will have access to the new store on March 25.
The launch titles are spearheaded by Square-Enix's Final Fantasy Crystal Chronicles: My Life as a King, which will set gamers back 1500 Wii Points, although it's hoped that the game will demonstrate the quality we can expect from the service. Less pricey are Nintendo's own Dr. Mario and Pokémon Ranch at 1000 Wii Points each, Hudson's Star Soldier R at 800 Wii Points and Tenchi Solitaire at a low 500 Wii Points.
The official Wii Ware website has more info. Although it's full of Japanese text you can find screenshots for all the launch titles.
