Simulated Worlds/Altered Pasts
Simulated Worlds/Altered Pasts
Stories where the mc either has a system to visit simulated/alternate worlds or can alter the past/memories of the past. Pretty much all of these are harem novels but a few are 1v1 or no CP, I'll mark the romance type and protagonist gender at the beginning of each summary. These aren't ranked or anything, just a casual list in alphabetical order. I'm always looking for more novels like these so recommendations are welcome in the comments:)

@Celceus
There's a few more that also fit, just not as good of a match.
Glorious God Throne, where the mc first goes to another world(?) with a different identity, and after living that life he can bring those identities to his current world.
Guidelines for role-playing rule-based strange stories, this one doesn't really fit but gives sort of a similar vibe. It's actually more of the infinite flow genre over simulation, but he has an extremely different personality and backstory for each 'world' he goes into.
Annoyed that 5 isn't finished. Read the novel like 3 times waiting for the MTL to finish because it just got me hooked.
I don't even care about the plot, I just want the MC to be happy because hs, the amount of tragedies he endured deserves a compensation.
