First fps game I ever played was ET: Wolfenstein, loved that game. Most of time I was just watching my brother playing on pro level, but played many hours too. Tried some COD, bf3/4/1 but didn't really like these games - just ffa games for kills, boring. Now the only FPS I'm playing is CSGO - started when everyone was playing it and I liked it a lot. I guess there is no any better competetive fps.
