I've played 1.6 and CSS. I mean, Source is a lot of fun. If you cant have fun playing source, then you're too serious to be playing computer games at all. I've been playing CSS everyday for about a month now that I got my PC back up and running. It's a great game and a lot of it just has to do with what server you are on and the skill level of other players.
Lets not forget, a major part of counter strike is just the mind games and sticking with your team and all of that. As far as recoil times etc, who gives a shit? I mean some people are such babies when it comes to games, I swear. If you actually really notice all that shit, step away from the computer and step outside or something to get some fresh air, you nerds.
