Earlier quoted context omitted.
But a lot of games are cute and fun to play that do not succeed
I'm not convinced that is actually true. Can you think of an example? A game that has near universally good reviews but is not successful?
The other thing that happens is you point out a really good game and then someone will say, yeah but that's not a good game because of the art style or it's too similar to something else etc. Everyone can always come up with a quality reason why a game didn't sell. Someone has a reason not to like every game ever made. The problem with that is you can come up with the same complaints for well reviewed games. Often the review will say something like : this has been done before, or that style is a little annoying, but.. it's a great game.
Final nail in the coffin of this theory for me is having talked to many game review editors and having worked with a few, they will often tell you that they don't always expect to shape opinion as much as parrot it back. As one person used to tell me, most people read our reviews to validate their purchase or get our take on what they are playing.
And then to your challenge. Good games that didn't succeed. How about Midnight Suns, Lock's Quest, Space Marine, Company of Heroes II, Maquette.. that's just off the top of my head. If I thought about it I could make a really long list of game you've never hear of. This is probably the same for everything: music, novels, etc.
