During my college days I used to play a lot of 1.6 & source...those were some good days.
I really haven't played this new version much but I feel this new game is only there for easy money by valve. Game feels broken enemies are hard to spot in higher settings & all the skins, knive,glove etc BS. I am sure many people play this now only for the knife & skins. Only thing which other versions of CS lacks is the competitive match making.
Once we had own a competition in our college then went on to play with other college. I still remember we went till the semifinal & was badly wrecked in the 2nd match.
But it was fun. If I have to compare our with skills with the skills of GO then I would say we were more or less like legendary eagles.
All those friends now got busy & we barely play.
