I toggle all map markers, play in very easy, and often toggle God mode in Fallout 4. I give myself like 200 stimpaks and 10k money in FNV with cheats, toggle map markers, and play in very easy.
I don't do this, butttttttt
I don't actually like the levelling aspect of RPG games; I enjoy the part about playing a role in a story very much, but unlocking new skills and/or abilities? Not so much.
In Skyrim, when I start a new game, after I enter the tutorial dungeon, I immediately add 99999999 experience points so that I can have
dozens of skill points, to allow me to cheat engine that number until I unlocked every skill in every skill tree in the game, I then "unlevel" my character to level 1 so she (I play a Nord woman) proceed to progress through the level-gated quests as the game intended.
I do the same in FO4 to unlock all perks. IIRC New Vegas worked slightly differently, since it used perk ranks and perk requirements. Anyways I hide myself in doc's house and grab all perks I want by resetting my levels before going out, in case there are level-gated quests being activated at game start. Another "trap" with NV's perk system is that, every time I level up and there's perk point for that level, I had to pick a perk; so when there's no perks left, I am stuck on the level up screen, thus I am forced to leave a good number of perks locked when I start playing the game.
I get that difficulty issue tho; Bethesda games are still stuck on the "higher difficulty = 3x HP 2x enemy DPS and nothing else" design philosophy. Gets annoying quickly when I have to smash some random mob in the head with a smithing-exploited Steel Axe of whatever OP enchantment repeatedly for a minute straight despite at max perk levels. And level scaling really makes worse, not better.
If only Fromsoft can employ a more "conventional" story-telling structure and use some kind of an in-game dialogue system... or someone else does it
