I just installed 1.6 and played for 30 minutes to get used to the aim. I went 62-4 on a public server. This game is so much better than CS GO. I wish they did some major update on it. +8000 hours and I don't regret none of it.
Thankfully it isn't the case and so there is room for better cs version to get released in future.
Hitboxes in 1.6 have problems. The game is worse in many technical ways. But there are the great eleements that csgo failed to transfer over.
Wouldn't be any good. The whole reason why 1.6 was as good as it was, was because of how the engine worked. The game would be ruined if it was built upon a new engine.
There is of, course, also the fact that Valve simply doesn't make games anymore.
movement - was a deep skill in itself unlike basic bunnyhop in cs:go, watch neo
sound - much better directional sound, guns sound much more satisfying to me in 1.6 especially AK and Famas.
recoil - when I occasionally play 1.6 I find the recoil a bit hard especially on m4a1 silenced, in 1.6 it seems to have more bullet spread.
Wallbangs - you could wallbang almost everything, you die a lot from wallbangs in 1.6. youtube.com/watch?v=W8A1q7ZAzp8
AWP - I feel you could be much more dynamic with AWP in 1.6, quick scope, scoped shot followed by no scope second one landed exactly where you aim
The only thing CS:GO does better is nades.
I still play 1.6 couple of hours for a week, although I’ve stopped playing csgo 2 years ago. Don’t know if it is nostalgia or what, but I get better emotions from playing 1.6 than playing go. These old assault, aztec, tuscan, mansion 😎
