just wait for hl2 or cs:source...if ur buying anthing now...since u'll be wasting money on these old things....
diff between cs n cz:
- cz has new high poly models (u can download free ones froma many skin sites)
- cz has offical bots... (tons of others here
)
- cz has single player mission (just get that hl mod that lets u play hl with cs weapons
...there are other mods..but none that have bots with though u could make one)
- cz cost more for basically same old game
so the final verdict...if u already got cstrike don't bother (NO) about cz
if ur got nothing wait for hl2 ports of these games (yes cz will also bet ported eventually
)
if u can't wait go get cz
