If I sign-up for the online membership (I have three free months that I haven't activated yet), do I get access to all the original Nintendo games? or just some? Or any? What are some of the other perks about the membership? And can you only play online vs. friends if you have the membership, or do you just need internet connection? Sorry, probably dumb questions, but again, haven't played video games in 9 years prior to buying the Switch for Xmas.
