This one is okay, but maybe wait for a sale. Trilogy of the Moon is set in the same universe as Eternal Rebirth –Curses of Love- which is available on Epic Game Store. In that game, you were the reincarnation of a King from 1000 years ago who owned 999 concubines, and you had to grant the wishes of some who had been reincarnated.
In this game, three concubines time travel from 1000 years ago into the modern day. Unfortunately they must go back soon, or they’ll cease to exist. All you do is hang around and help them navigate the modern day before they leave.
Since all three admirers are fish out of water, there is more natural humor than in Eternal Rebirth. While this helps the experience, the game does not leverage it enough. The three admirers aren’t deep or interesting, and none of them are standouts in the genre. It is just a typical setup where they like you from the start and you occasionally pick one of three to get close and earn affection. Incidentally, affection is cumulative, so you must explore many branches to unlock the endings.
The main setting is a large house that was also used in Come on Fantasy Baby! (Epic Store). This game seems to be made in conjunction with Maxim Korea, which is why the admirers are photoshoot models. And that’s probably why the story is fairly basic, succinct and short, taking 1.6 hours first run and 3.3 hours to see everything. While cleavage shots are common, this game is not as lewd as Eternal Rebirth or Come on Fantasy Baby. However, Come on Fantasy Baby is a slightly better game, and My Love with the Girls Group (EGS) is still the best Korean game of this type in my opinion.
