Sometimes I wonder why there's cheat codes, or how the programs like Action Replay are even released. Seriously, why would you use cheat codes? They defeat the whole purpose, and challenge of the game. The only reason I see to ever use hacking material is to find out clues, and secrets to games. I see alot of videos of people using cheats to get to a high round on zombies, or to achieve a 50:0 killstreak without doing it fairly. Cheating in other games like pokemon to get rare Pokemon unavalible to the game is even more useless to me. They only ones that halfway matter are the ones you get from mystery gift, or for winning a competition, or something. If you can't get it without cheating, you might as well not at all.
The top of the leaderboards in Zombies in Call of Duty: World at War has always people that has "reached" playing Solo to Round 2147 (not exact amount) without even killing one Zombie because of the use of cheats.
In Mario Kart DS, many people have "won" 9999 races using AR.
I prefer taking a very long time clearing a game without using cheats
There's always someone that ruins the fun in every game that can be played online. Before, I used the Action Replay all the time. Used it online in Mario Kart DS. But then, all the codes were erased. After buying my second AR, the same thing happened. That's when I realized cheating is stupid, and it ruins the fun.
