Pros:
- The game is very balanced.
- For competitive play, it's one of the best out there for teamwork.
- There are operations and hundreds of community servers with innovative game modes for you to try. It has massive longevity.
- Trading is an extra aspect of the game, and if you really invest time into it, you can actually make money by selling cases/skins.
- It's one of the best games to watch professionally.
- Casual games are very fun.

Cons:
- The interval between operations is quite long. I think it should be shorter.
- There's a reasonably steep learning curve, so it may take a while to really start enjoying it.
- Sometimes the community can be toxic. However, if you find a group to play with, you're good to go.
- You might end up spending more money on the game for weapon skins, as they are quite nice.

NOTE: There are many players complaining, saying that the game has too many cheaters when it doesn't. The real issue is that these players, when they get too many headshots, can't believe there could be someone better, so they resort to cheating software to try to keep up (but they eventually get VAC banned). Or they simply become haters of our beloved Counter-Strike and start spamming about cheaters, complaining there are too many of them, and so on. Please, stop complaining, learn to control recoil, practice good strafing, and especially try playing maps other than Dust 2 and Mirage.

Given these considerations and small observations, Counter-Strike is simply the best FPS franchise since 1999 and will continue to be. No more to say.
