There should be both. And there will be both. I hate this whole boring subject that Nintendo has injected into the conversation. If it's an attempt to bring in non-gamers, great, the more the merrier. But I am a gamer and I honestly like both types of games. Some games aren't worth the complexity, but many just allow you to do more than you used to be able to do in a game and that's great. And simplicity is sometimes right, and sometimes feels retrograde and frivolous. A lot of those games in that list that are "innovative and simplistic" are fun. And some are fun for about 2 days and should probably be on a cellphone rather than $30-50 on a dedicated gaming platform.
Quality isn't bound up in either simplicity or complexity exclusively, and I don't know how it can be simply shoehorned into one or the other for the sake of some debate.
