This is not about popular games that are actually bad. This is a thread about all those games that are super popular but you just stand there and watch and don't get the hype.
For me it's definitely Ace Attorney. I mean, I don't think it's bad, it's pretty lighthearted and nice enough, but I never understood why it blew up the way it did as I just see nothing special about the series and a lot of its elements annoy me to death.
