I only use cheats once i've satisfied myself that i have wrung all the non-cheating enjoyment I'm going to get out of the game. it was more of a pre-internet stratagem for the now ubiquitous youtubing of a game's ending. Only games that come to mind where I cheated to a flagrant degree were Battletoads (obviously) and the original Turok. Oh, and also Mercenaries. Final area is brutal in that game. And item duping in FF:Tactics.
Some games improve with cheats. Especially those of the open world variety.
