Because sometimes it's more fun.
Mines just modded for pretty much the same reason as wiggles.
Modded zombies for fun, 10th prestige on Cods because i get bored too quick so getting it legit would be near impossible for me and i modded Gow rank 100 because i wanted to look cool
I modded my Red Dead Redemption, nothing's cooler than a Grandma riding a Zebra Donkey... I mean come on people, A GRANDMA ON A ZEBRA!
I mean I understand why they do it. But sometimes it gets to be annoying like kids with modded controllers and what not. They shoot me with like 1000 pistol shots in a second.
I don't got time to do it legit. Its just a waste of time to spend 1 month ( every hour) to get to 10th prestige, so i just hack it. Was a lot of fun when we could still host. i miss the good days.
I used to mod but then it got so boring.
Well it seemed the only way to play a match in Halo 2 would to cheat because everyone else did. Thats how i got into modding. Sience then I only did it when I got bored. for example after I beat a game I will mod it just for fun.
In my opinion its funnier to play then.
They mod there games to play something new and not the same every time. Mostly its a lot of more fun with mods.
Just to have fun I guess.
