Yes. Cheating is a very fun way of playing certain games. Spawning opposing armies in Jedi Academy, ridiculous power spam in Battle for Middle-earth, messing with NPCs in Skyrim, getting yelled at by Smiling Jack in Bloodlines, infinite jumping in Dragon Age: Inquisition, etc.

Well, modding is a form of cheating and you can't call yourself a pc gamer until you've modded a game, usually making it better or more enjoyable in the process. So, hell yeah.

Edit: Oh, so you meant cheated when playing multiplayer? Hell no, never have, never will.

i use a cheat on cs (the 1.4 or 1.5) because a friend told me that was fun, we joined a random server without anticheat and had fun for a while, later i uninstall it , but some .dll stay on my computer.... bad thing, because at that time i was playing on clanbase and a server blacklisted me for that stupid .dll -.-

I don't really believe in cheating.

Yea when I was a kid I played cs 1.6 with cheats. It was really a lot of fun...:D Got permanent ban on 99% of the servers from my country..hahahaha :D

I cheat all the time in single player because I suck, but never in multiplayer, it kinda suck the fun out of it.

no

I've never cheated in multiplayer purposely. Although back when MW2 was full of hacked lobbies and you couldn't avoid them I had cheats used on me. I got hacked to be the highest level possible. It wasn't of my choice for this to happen though.
I would never cheat in a multiplayer game unless I was playing privately with friends.

nope

Shame on cheaters!! I really don't like people who use cheats in multiplayer, how can that be fun?

never ever before

Well, I earned all "cheats" in Goldeneye in my N64.
Always wanted to cross the water at the dam...

About multiplayer

I used hacks a few times when I was kid, specially on pirate Chinese servers of Metin 2 MMORPG to walk faster and don't waste tons of time going from one part of map to another, everyone did that, and since it was not an official server even game itself was cheated already like super fast leveling up, very high drop, etc. I also used Transparent texture packs and flied very fast(with mods, not hacks though) in some Minecraft servers, it was shitty, so never did that again.

About single player

I used cheats(AR codes) to get stuff, or pass walls, etc in single player Nintendo DS emulator games, like Pokemon Pearl, it ruined me the game experience and I didn't touch this games for a very long time, now if I use this AR codes I use them only for things like fix bugs, going to hard mode in Pokemon Black 2 without having to beat it on normal first and then unlocking hard(also in this game unlocking hard does not mean NG+, it means delete you save and start over lol, very stupid imo, better I start from hard from begging), or transferring my Pokemon from gen 4 to 5, because without console is not possible to do this without cheats, now I may use save editor in some games, but only for things I consider very stupidly implemented in game, like beating game tons of times, cannot change name, cannot change appearance, cannot redistribute skill points, etc.

I've never cheated in multiplayer. Don't like false competition and all that.

Single-player, I've done it for a number of games. Mostly if I was getting bored/annoyed but still wanted to see how the story ends.
