Would-Be Prince
FGO is considered a melding of almost all the fate timelines, as it takes place in the scenario that all of human history must be saved. In which case timelines like that of the original Stay/Night arcs and the Apocrypha story meet together. It’s true that it does have it’s share of ridiculous episodes and fan service events, but that’s a consequence of its medium more than the content. I’m perfectly willing to allow other versions of servants extant in FGO, and I will judge them the same way I judge original servants. If you want to pitch your luxurious Cleopatra then go for it, but I will probably ask you questions about why she acts a certain way.
