"Anymore," you say? :P
It's a miracle WiiWare was made at all, considering the incredible limits developers had to work within but on top of that, if you bought a lot of Wii games with online components, since you couldn't move or copy the resulting data file, and WiiWare required to be run from internal memory, I imagine there would come a time when you would have to choose between deleting a save file or being able to play a WiiWare game. o_o;
Most of the titles were simply crap. For example, Harvest Moon: My Little Shop actually punishes players for unlocking more of its minigames. That's why when seemingly good ones like TMO get lost, it's a real shame.
A few titles got ported to iOS, but ports are not the same. They never are.
