I love your dedication, you're doing everything (about Shuffle) I had been planning to do in the last few days, that's great.
As for Over the Rainbow: I think scores is out of the question, especially if there is no counter (...is there one?). And gs93 made a good point.
I also don't think stages is a good idea. In story, you can't decide which one to go to, that'd be long and painful especially just to play the 4th Dimension. And even if done in Versus mode, the stages are just way too long, and it too much random based. Sometime random is good, it you can manipulate luck enough (i.e. Hunting stages in SA*), but that's taking it too far.
I also think we should look at mini-games that are really easy to max-out, in terms of rings, best score and best time. We usually let these kind of stages here on TSC just for completion, but if Shuffle happened to have too many of them, maybe we should remove some.
As for how to get it added, I don't think the problem lies on if it'll be accepted. Hell, Sonic Jam for the game.com
got accepted, for purposes of general completion, and I'm the only one who probably even has this game here. The problem is that Rolken is really lazy, like "holy shit how does the guy even manage to walk" lazy. :P And to add to thigns, he's not really here anymore, something about visiting Europe, I dunno.
EDIT: what the- there's a 3rd and 4th page?! Oh well, I hope I'm not too behind on things.
And yeah, I've mostly just been talking about Shuffle, but I'd be pro Sonic the Fighters as well, even though I have no way to play it (except some lousy emulator), and probably wouldn't compete in it either.
