For sure, the best FPS.

Pros:
- The game is very balanced;
- For competitive games is one of the best out there for teamwork;
- There are operations and hundreds of community servers with innovative gamemodes for you to try out. So it has massive longetivity;
- Trading is an extra aspect to the game, and if you really put your heart into it, you can actually make money from selling cases/skins;
- It is one of the best games to watch professionally;
- Casual games are very funny;
- It's very cheap.

Cons:
- The interval between operations are very high. I think it should be shorter;
- Reasonably steep learning curve, it may take a while to really start enjoying it;
- Sometimes the community can be toxic. If you find a group to play with, then you're ok;
- You may end up spending more money on the game for weapon skins, as they are nice.

NOTE: There are many bots crying, saying that the game has too many cheaters when it doesn't. The cheaters are themselves that when they take too much headshots don't believe that there can be somebody better, then that these s**t begin to use softwares of aid to try to be good as we (but they get VAC). Or simply they become haters of our dear CS:GO and start to doing spam to don't play competitive games, there are too many cheaters and bla bla bla.
Please, stop crying, learn a recoil, a good strafe and specially play a different map of dust 2.
