My first experience with it is... interesting. I thought the concept of the game was really cool and I thought it would be fun to try it out. But as stated in previous replies, you got to get used to the spray patterns, the walk speeds, etc. and this may be biased, but when I tried asking for help on how to play in chat, it was either people saying "alt+f4" or just not responding. After dying a number of times without getting any kills at all and not knowing how to play, I really moved away from the game after that because I don't want to go through countless hours of understanding the mechanics for the game. As stated as well, tf2 can either be fun and silly or really competitive. CS:GO thought is just all competitive, and that isn't really my style.
