I used to be a Halo 2 modder. Hacked games I played are the early halo series but I was only 12 years old at the time and stopped doing it by age 13.
I haven't played any hacked games - it's just too risky because you're installing software that can potentially do harm to your own system.
The thing with playing some of those games is that the fun will definitely end soon because of how easy the game may end up becoming. You won't have the urge to continue, and that is where it is likely to end.
