To be honest I was considering giving this game two stars just because Fate girls are hot no matter what, but this game just butchers everything to the point the only similarity between this and FGO is the characters (mostly) look kinda similar.
The most obvious problem with this game is the obnoxious and hard to read dialogue, which leads to boring sex scenes, which you get to through the repetitive and nonsensical game play. Funnily enough this game manages to even have a tone problem, which should be really hard to do considering you have the characters and story written for you already. One moment your in Orleans and you use a command spell to fill Jalter with lust and she sits on your face behind some bushes (which beats her I guess). Then when you go to Oceanus, you find out that Mary isn't with Anne because... Blackbeard killed her while he was raping her, which is just kinda, uh, blown over and not really addressed at all really. There are a lot of other things I could mention, like the fact the master is almost always being dommed in the scenes, or the fact that animation sounds nice until you realize the camera is like three blocks away and there is no text during it, or perhaps the fact the dev got super lazy and had four combined sex scenes (only two with penetration) in Septum and Oceanus and gave up on doing anything with the servants after the fact. This is maybe the most disappointing game I've played on here, the way the game is made in the first place is just so fundamentally bad it's unsalvageable, couldn't get past London before I just had to uninstall, don't bother even trying this out.
