It happened with 1.6 too to a much lesser degree because Gooseman and Cliffe still had massive input and obviously...the game was a lot smaller.
But when 1.6 came out in late 2003 , more than half of the playerbase hated it, they hated the massive jumping accuracy nerfs, they hated the increased inaccuracy of AK Spray, they hated the movement glitches and bhop staminna glitch above 100hz, is just that the game still retained a lot of its earlier versions traits, in any case, if you would've been able to properly poll everyone in 2005 who had been playing CS for at least 4 years, they would ALL have told you that either 1.3 or 1.5 was the best version of counter-strike, and something important to point out is that it wasnt nostalgia, because at this point the same players who denounced 1.6 had also previously praised 1.0 over Beta7 and 1.1c over 1.0 , there was genuine progress and increment of the skill ceiling as those revisions launched, but then again...those tweaks were 90% Gooseman and Cliffe , 10% some VALVe retard who thought his bot vision was actually the future of counter-strike (how fucked up is it that he was right in all the worst ways?)
But im sure you already knew all of this, even if you couldn't put it in words before, it's just tragic when these corporations take something that isn't theirs, suck the soul and essence out of it, and the masses to which it panders eternally defend them with sword and shield, completly taking a massive shit on those of us who liked the real thing from which big corpo got its golden egg.
If you look at how Id Soft. treated Quake and how Blizzard treated Starcraft , clearly, those big corporations which are supposedly much more unethical than VALVe have respected their iconic franchises much more, Starcraft 2 is a great continuation of Starcraft, Quake Champions is not a good continuation of Quake Live , but it is still much more recognizable than CSGO 2023 build to 1.6 , let alone CS2 compared to 1.3 or 1.5 ....or frankly....even source.
