MLP: just saw some MLP mods on Team Fortress 2, then, I saw some animations made by the community and more until I fell in love with the show.
PAYDAY: I saw Bob Lennon and Fantasio974 playing it and I wanted to discover more about this game, in 2015, I got it and I love this game because of it's RPG elements in a PvE shooter. I'm still playing it after 1960 hours.
Team Fortress 2: My first FPS game that I spend more than 100 hours when I was a kid and searching for good multiplayer games, and still playing it today! 4200 hours on the cloak and still counting!
Yakuza series: Saw JFJ playing and those games are so fun to play and the violence is perfect! Funny, yet brutal.
