this game is not worth buying bc it got replaced by left4dead 2, you can play the left4dead1 campaigns in the second one and this game makes me lag even on my own servers, it has worse optimization, hitreg is worse. the left4dead2 versions of the left4dead 1 campaigns are harder but still. there are 5 reasons i can think of why people still play this game. 1. the maps are easier as there are no jockeys or spitters, no spitters means u can be a camping ape in certain spots. 2. some people prefer the older versions of the maps because there are things in the left4dead2 ports that you cannot do. 3. mechanics are different. 4. achievements 5. nostalgia.
