Some removals likely the result of a studio closure, while others lack explanation.
Various WiiWare titles were recently removed from Wii Shop Channels all around the world.
GameArts' The Magic Obelisk has been removed from the North American Wii Shop Channel. No reasons for its absence have been given by the company or by Nintendo.
In Europe, several more games have been removed. Hudson's Shootanto and Diner Dash and Nintendo's LONPOS are among the casualties, but once again, there are no reasons given on why these games are gone. Zallag's Racers' Islands games and Gods vs Humans are also missing.
Zallag announced the studio closure in May, which may be related to the removal of their games in Europe. Talking on his personal blog, founder David Jeuvideo talks about what led them to their downfall: ''The situation was complicated. Our games came out at a time when nothing was happening on the Wii. So even being in the top of the sales charts, we didn't gain anything in terms of money. Most journalists don't even review games from the on-line store. It was difficult to know our games from WiiWare.'' Further, it was mentioned that thanks to the poor WiiWare sales, they didn't have the resources to continue development on future properties.
All of Zallag's titles are still currently available in North America, but it is not clear if they will remain there in the long term. Likewise, the majority of Hudson's games remain available, despite being absorbed by Konami in April.
