Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!
As far as this thing goes... change the name you boob. I would argue this is worse than Ayds candy. They at least have the excuse for existing before another popular homonym entered the public's vernacular (though they get nothing for noticing this and changing their name to... Diet Ayds). Soylent green I feel is one of those things that has transcended pop culture. Even if you've never read the book or know nothing otherwise, everybody knows that "Soylent green is people". You're basically asking for trouble for using the name.
I can't countenance why an entrepreneur with a severe need to have people critically examine his invention would give it a name whose cultural associations would provoke people to critically examine his invention.
Regarding the trademarking info: scuttlebutt from Reddit is that legally speaking you're required to provide a trademark or copyright notice on each individual artwork in which a particular trademarked or copyrighted item appears. The game's package counts as a separate work of art from the game itself, so Nintendo is only obligated to provide such notice on the packaging for those characters that actually appear on the packaging. Meaning this provides no evidence in either direction as to which characters are in and which aren't.
What hasn't changed about Nintendo, I think, is that they tend to make really great second systems. If you have a PC, XBox, or Playstation, and you want to pick up a second system, you'll get far more out of a Nintendo system than you would get out of picking up any of the other three. Nintendo isn't leading the pack by fifteen miles, crushing the competition and salting the earth behind them, but their niche is a stable one that's continuing to work well for them.
