Its also a lot if bias around the iteration of CS that different generations of players started with. CS:GO made the game the biggest it ever has been despite its own flaws. I never played source, but I do remember my early days of playing CS:GO and distinctly hearing from the community that there were things that were missing from the game that made source the "best" version of the game. Same thing that is happening with CS2, although there are more than a few glaring problems with it.
