Crusader Kings II - Shooters are for kids. Retaking the Holy Land is for men.

I mean, it is not that rare of a type of gamer. A lot of Let’s Players are also like this, playing just one or maybe 2 games for their channel and still drawing an audience.

I am personally not like this, but I respect this way of gaming, nonetheless. Some of the most skilled players can come from this style, like people who only play Smash Bros. or an MMO, a genre ideal for that one-game style.
