Should we really have cheats openly available everywhere in the game?
For instance:
All the rules should be optional. God mode from the start.
Pop up option to skip a battle before it starts.
We should have every ACTS available from the get go. So we pick whatever point in the game to start from.
I'm not going to lie, after doing 2 playthroughs it would be nice for an act selector to relive parts of an act without having to replay the entire game again
But honestly there's systems that have implemented this successfully like Xenoblade Chronicles 2. In that game (past v1.3) you can change how much HP enemies have, how hard they hit, how effective debuffs are, etc. You can also just use the preset "Bringer of Chaos" difficulty if you wanted the traditional hard experience
These QoL features respect the player's time and lets them play how they wish. For example given the chance I'd want to play BG3 on normal as that is what the game considers the "intended" difficulty with normal HP, normal shop prices, etc. but also experience the enhanced AI tactician has
But with these sliders you could also get your ideal "hardcore experience." You can have an option to turn off withers, turn off waypoints, to increase shop prices as much as you want, give enemies 300% HP, etc. Really giving the players more options on how they want to experience the game they usually only helps the player's experience
