You should really watch AVGN's take on them. Those games deserve to be on that list without questions asked.
Actually, Zelda's Adventure is a much better game than the first two. The first two, the sidescrollers, yeah, they belong on the list no question. But Zelda's Adventure... no, not really. Apart from the several second long loading times between screens, most reviews agree that it's not actually that bad...
A lot more people played the sidescrollers though, and that's definitely where most of the 'CDi Zelda is awful' reputation came from. Zelda's Adventure was one of the last CDi games released in the US (in late '94; I know the CDi lasted years longer in Europe, but here that was not the case), and it's a quite rare game, so not many people actually played it. See this video review for instance:
http://www.youtube.com/watch?v=_MHy7OD4r1I and note that if you watch the other parts of the series, he HATED the two sidescrollers and thought they were some of the worst games he had ever played. Yet he ended up liking Zelda's Adventure.
Anyway, Pac-Man 2 and Mega Man Soccer are also pretty bad choices. Sure, some people dislike Pac-Man 2, but plenty of people liked it too. It's a fine game for what genre it is. And Mega Man Soccer was a perfectly decent soccer game. Bashing games just because they're in a different genre from past games in the franchise isn't right if they're good games in their genre, I think. I mean, if they were canceling the sidescroller Mega Man series and replacing it with only sports games or something then complain, but one spinoff soccer game or a Pac-Man adventure... why not?
And yeah, stuff like Sonic 360 and Sonic the Hedgehog GBA absolutely should have been on that list...
