What's the difference between CS 1.6 and CS:CZ? : FPS / MMORPG / RTS Discussion

it seems to me that more ppl prefer the former of the counter strikes and i want to know why. Obviously it isn't gameplay or storyline, so what makes it so much more appealing? Is it more flexible with hacks, exploits, mods and the like. In otherwords, is it easier to mess with it. And does it run faster or something?

Counter-strike: Condition Zero is a fraud of CS 1.6 its suppose to be an upgrade, but just causes bad quality and poorly made engine, its not worth playing and cs 1.6 is closer to 1.5.

Ofcourse will it run faster as the game is much older
i think there is several reasons why people prefer 1.6 much more than CZ or Source. One of the main reasons is that it needs much more skill and its oldschool. Some people dont have a new computer so they will just keep playing 1.6 as theire source is lagging. Personal i like 1.6 better than source even tho i only got source
