Topic: Sonic is still up.

I checked the Wii Shop Channels from both Nippon and the United States. Sonic the Hedgehog 1 and Sonic the Hedgehog 2 (the Genesis versions) were taken off only the shop from Nippon, not the one from the United States.

Would you really care if they were? There's so many possibilities to play these games it doesn't really matter.

I think everybody who would have downloaded them would have already done so by now.

I thought the Sonic games were already removed once before from Japan.
I thought it was something about the Sonic theme (title and invincibility music) that Sega had licensing issues with, possibly just for Japan.
Although if anyone remembers Sonic Spinball, it seems there was an issue where the title screen music was replaced. Reportedly a small amount of US copies have the Sonic theme (which is thought to be first-prints) while otherwise most copies worldwide have a different song.

or moved on already but so many people trail behind because they want to be against the WiiU

Since I still have the original Genesis carts, as well as both Sonic Gamecube collections, I never bothered to get the VC versions. Since they might get pulled though, I'm gonna try and get them all before they do. Just got Sonic 1 last night. Next up will be Sonic and Knuckles because of the lock-on emulation, then hopefully I can get Sonic 2 and 3 before they are gone.

I dont get what difference it makes anyway if they are in the Wii shop or not

Well, in Wii U there is the only way to play this games, via Wii menu of course. I already have Genesis collection on Gamecube and 3D versions in 3DS. I don´t know if download them, maybe Sonic 2 because you can use Knucles if you download Sonic&Knucles in Wii. Maybe to download them to have a rare game in my Wii. I don´t know. I preffer to use that points in a lot of games I wish in the Wii VC that I still have in my wishlist.

I remember this games were deleted in Japan time ago.

Its still unfortunate that there isn't Genesis support for the Wii U. The GBA and DS Sonic ports aren't worth getting if they ever come.
