Without Modding we would of never had Counterstrike so i like Modders. They are awesome they create some awesome stuff for games and some games such as Vampire Masquerade Bloodlines which was bugged to shit some of the mods patches make the game more playable and a more enjoyable experience.
So modding in game content is very cool and also helps the gaming industry.
Hackers on the other hand take the piss. Ive never encountered one but i rarely go online with gaming(although Dead Island has me very tempted to renew my Xbox Live). But i dont understand cheating at all especially with online games, just as i dont understand why people would buy a high level character for money when part of the fun is leveling the character up and customizing them to how you want them.
But didnt that kid get arresting for hacking Call of Duty servers??
