Is this better than Sims 4 modded ?
IMHO
It is a bit a of an unfair comparison as the Sims 4 was first a full fledged game, then the adult content came, so the overall experience (UI/UX, gameplay loop, interactions, etc), is still better in the Sims.
But when it comes to adult content, actual adult content with repercussions, kinks, storytelling,
context. That is where this game beats the Sims easily.
A couple of thing I feel would benefit LP in this "race" is UI/UX (which at this point I think is a must), and the possibility of playing multiple characters (or having control over their actions to some extent).
