This. There are a lot of online games I loved playing but the cheating got so bad it made it impossible to play. MW1, MW2, Battlefield, CS, etc... you could see the wallhacks and aimbots taking over every lobby. I eventually stopped playing. I tried using Consoles for online gaming after that but never really got into using joysticks.... still prefer mouse and keyboard. Now I play limited games where the cheating isn't quite that rampant.
There are still some servers online for games like the first CoD or United Offensive. No hackers as far I can tell anymore. They have all moved on
Im not a big gamer, but playing GTA Online, and getting taken out as soon as you spawn. Or items just spawning in front of you, like ramps. REALLY ruins the experience
