I Counter-Strike 1.6 and Condition Zero already had the decision was not easy for me, got it but then bought.
What I had noticed first of all that Steam was faster and especially more servers had found than in the other games. Thus one often finds even maps that were almost never available at 1.6 and Zero. A really big plus.
The graphics I find that very beautiful for Counter-Strike and enhances gameplay greatly.
Even the Revised sound is excellent (Example: Explodes beside you a grenade you listening for a time everything very quiet, dull and poor in a flashbang one sees nothing and has now new to CS:. S also experience ringing in your ears, so the we also briefly hears nothing.)
I personally like CS: S better. Can anyone say what he wants. I find it simply beautiful and realistic.
Only downside is this very steep price. Because of "just" an improved remake's nevertheless already steep.
If everyone left alone :-) I repent buying Never.
