/UJ what's a popular video game series that you don't hear a lot of people talking about?

My example would be Halo 5. It sold really well, and there's a lot of activity on r/Halo and discussions about it on r/Xboxone. But outside those subs (because of course Halo would be talked about on those subs :p) I never seem to hear many people talking about the series. It's kind of weird, but also probably overshadowed by Fallout, Battlefront, and COD.

Any games that you guys know of that seem really popular and/or sold well, yet not many people are talking about it?
