I never really had a bad problem with hackers on any game on PC but I also play a lot of Xbox 360 games as my machine isn't powerful enough to handle more than Portal 2. The first time I loaded up the Orange Box, my very first time it was on Xbox and boom, hackers. Nowadays that doesn't anger me much because I don't play TF2 on my 360 anymore now that I got it on PC.
Now there's a new epidemic of hackers and a couple of my other favorite games. Call of Duty: World at War and Modern Warfare. Now before somebody jumps down my throat about CoD, I am not a fanboy and in-fact the thing I hate most about the games are the community around it. Anyway World at War was my first FPS and I liked that CoD more than any other. Of course now I can't play and it pisses me off and makes me wonder why? Why do people feel the need to ruin the experience of other players who just want to have fun playing a game they love.
This isn't just about CoD now, it's about all games that have ever had a hacking problem. I wasn't around during Half-Life's release but does anyone else know if it's MP ever had a hacker problem. I'm glad it doesn't now anyway because I probably play that the most out of all MP games.
