I've ruined so many games with "god mode" hacks that way. Even something like giving the player obscene amounts of currency and continuing the play the game "as normal" afterward slowly killed it.

So, I save that kind of thing for _after_ the 100% mark (or even 90% for some). When I'm done going as far as I plan to go, then I open up the hacks and mods and see what craziness awaits.

The video games analogy goes even further: playing Doom growing up I'd always enable god mode because it was slightly scary, so it was not a super fun game for me despite being such a cultural phenomenon. Similarly, cheating and getting all the answers/saves from a machine robs the satisfaction of the journey. And we're all strapped with cheating machines.
