Review Detail of NihilRuler in I Am The Game's Villain

so will this one be a harem (more than one wife )

Yes. But the Harem will be built originally and logically with some games elements.

No…. I don’t like harem….

sorry...

will you write r 18 scenes??

Not really, there will be intimate scenes but not that

is the character of MC good and like helpful? I hope MC nature is neutral and thinks about the advantages in act

His primary goal is to survive so to avoid the bad ending so he won't save people here and there. Not the cliché kind protagonist

in survival is there a moment he will falter to save and help other characters because of empathy? hope not

If he saves people it will be for 'other' reason, don't worry.

Yandere?

If you ask whether there will a love interest with dangerous tendencies toward the MC, then yes...

Ntr?

No.

Hopefully the harem size is not big. 2-3 is very preferable. Your writing is competent enough to make it satisfying and realistic ad possible.

mc will date with the heroines?

Yes but I will not spoil which one...

I mean with ALL?

Of course not. It will not be that cliché and obvious

So far it is a bit confusing as a story, though each of the characters are rather unique. The MC is definitely not a hero or even anti-hero, he is a villain in his personality and how he treats others. Probably has a bunch of issues to work through before he is even willing to be anything but hateful to everyone.
