Only time I used cheats was Game Genie codes on ZSNES while I was ****ing around with Link to the Past. It was mainly the "walk through walls" cheat, then getting all the items so I could mess around in parts of the game you aren't supposed to get to. I ended up finding a piece of heart that isn't in the "normal" part of the game.
The only other time I "cheated" was using the
Challenge Glitch in Perfect Dark (on site, 7th down) I simply didn't feel like beating all those challenges; Me and my friends just wanted all the unlockable weapons for multiplayer. And multiplayer was fun.
And occasionally it's fun to put a hidden teleporter in a Halo map that leads to a sick weapons cache, and take out the people that camp in tanks right next to where everybody respawns.
Now, other than those instances, I'm a pretty legit player.
