The first feature a demon that at one point made contract with the villainess of the game when the latter was very young and wanted a friend.
Then later on the demon was informed that first contract has yet to be fulfilled and is preventing her power from growing.
So through the power of her boss, she got sent back in time to revive in her old body, which then get isekai'd and meet said villainess.
The otome game in this one is an MMO where players try to trigger events and 'win' by getting their happy endings (like marrying the prince for the obvious one)
Except that game was made by the 'goddess' of this world, who then isekai the people who did well in the game to tempt them to recreate that scenario to make the country prosper.
Obviously the demon don't give a fuck and anyone daring to harm her ojou-sama get murdered.
(Someone is translating this "Miss Demon Maid")
The other one, same author, have the MC meet not-God after dying to save the new 'savior of mankind' (said not-God is the previous one)
She asked to be sent to the world of her game,but he explained that those worlds aren't really game-world per se, but rather someone has a dream of those world and make a game based on it.
She still want to go, and he send her off.
But the next thing she know, she woke up as a villainess of an otome game, which turn out to be the same world as the MMO.
So she decided to gain power so she can fight against her fate.
While also realizing the characters in the game are all kinda fucked up.
Like the heroine isn't the sparkly eyed innocent girl as portrayed, but a psychopathic miser that somehow has the brain that only interpret things in her favor.
