Now I have more than 1000 hours in Counter-Strike: Global Offensive and I can finally express my impressions of it.
Even though the game consists of 8 repeating maps from the Active Pool, every match here is special. You use different tactics, move differently, interact with the team differently. In general, the gameplay would seem monotonous and boring, but no. Many modes and fan modifications do their job. Don't like serious gaming and just want to play for fun? Go to the public page. Tired of shooting your opponents over and over again? Go to DeathRun, KZ, Hide'n'Seek. The game is surprisingly diverse in this regard.
Graphics are a rather specific parameter for this game, because it was released back in 2012. However, the new redesigned maps like Nuke and Inferno are quite picturesque and beautiful. I would even say it's reminiscent of the games of 2015-2016.
An important innovation since the classic CS 1.6 is the presence of matchmaking - a kind of analogue of the mixes of that time. Unlike regular modes, leaving it is punishable by a temporary ban. The players here play not for fun, but for the title, so most are super serious. The downside of this mode is that there are a lot of cheaters in it, whether you are prime or non-prime. In general, about cheaters. Although with the addition of Prime there were fewer of them, they were not completely eradicated. You can still meet arrogant spinbotters who never get banned.
In general, the game is a graphically improved Counter-Strike 1.6, where instead of free mods there are skins, however, this does not make it any worse and it is still the same classic cs.
