Coming from Zallag founder David Jeuvideo...
"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."
The company ended up losing money on their digital products, and thus the company folded. Now we have the full explanation as to why the company's games have been yanked from WiiWare! Thanks to NintenDaan for the heads up.
