Why do people hack?

some games were just meant for hacking. gta vice city and san andreas for example. its so much more fun to spawn tanks n planes n helos n cars and abuse it in any way you can.
multiplayer hacking tho... i used tp hacks on private wow servers to grind to max lvl faster for example. but some straightforward hacking thats making things unfair in pvp, there was the red line for me. im an old school cod player for example, and in early years I always wanted to get to that end game where purely skill and experience would overpower enemies. That made me feel good. Sure I turned on hacks in my lifetime on cod also but it was maybe a session or two after which i stopped playing the game at all for a few months.

tldr. some games are more fun when exploited, its a bitch move to use those exploits to gain advantage in multiplayer tho.
