Now I am relatively unlikely to use Cheat Engine for xp. Yes, you can turn your level 1 character into a max level character, but then the game just becomes boring as hell, because you are still in that level 1 zone. There are quite a lot of games on which I never used Cheat Engine at all, because I found the game fun and balanced as is, and didn't feel the need to modify it.

The one value I am most likely to modify in a typical RPG is my gold, or whatever other currency there is. Because by the conventions of the genre, you are supposed to collect junk loot while adventuring, sell that junk to traders in town, and earn much of your gold that way. I never liked that game mechanic, and I am certainly not using that in my D&D campaigns. In computer games, it depends on how it is implemented. I especially hated Fallout 3 for this, because there were literally hundreds of containers to open in any locations, and most of them contained junk of very low value, so you really had to haul quite a lot of junk to earn currency, and spend half of the time in game opening drawers and boxes. I prefer loot systems like Diablo, where relatively little loot is coming from the archetypical barrel, and a lot of the stuff you sell is armor and weapons from enemies. You take the best stuff for yourself, and sell the rest. My dislike of junk also depends on how restrictive the inventory management is: After playing some Larian Studios games with horrible inventories, I appreciate in Wasteland 3 that there is absolutely no limitation to the number or weight of the stuff you carry around; not so much of a hassle to sell junk if it doesn't block valuable space in your inventory, and there is a "sell all junk" button too!

But when I get to the point in an RPG where my characters are overloaded with vendor trash and I am supposed to travel back and forth just for the gold, I am likely to pull out Cheat Engine instead. Leave the junk armor on the corpse, and POKE myself some gold. I want to play heroes, not trash collectors!
