I used to play FPS a lot. In the following order:
CoD (2003)
CS:S
ETQW
TF2
CS:GO
youtu.be/lR5UGc4llzo (I was a badass soldier class)
I also was into MMO's for a few years (Lineage2, Aion; spent $3k irl money on gear---idiot)
Then I fell in love with strategy games (like chess). Loved starcraft2. Got to diamond as a zerg player.
