I play CS 1.6 more for the thrill than for the skill. Sometimes I want to turn it on in the evening and run a couple of rounds on de_dust2 without stress. With bots, it's convenient - turn on the desired difficulty and play at your own pace.

Recently, I found a version that includes everything already built in - the bots themselves, a convenient menu, and even a pre-configured list of maps. I didn't have to finish anything, just downloaded it, and everything worked from the first launch. I stumbled upon it by accident, leafing through the selections - there was the usual banner, such as 'Download CS 1.6' I clicked without much expectation, and it turned out to be just what I needed. Since then, I have rarely go online, you can relax.
