Does FGO have GBF-style week-long recruiting/ranking events? I just assume they do because that's what drives a lot of these games as service gacha games.
You mean stuff where there's a bunch of players competing indirectly via a higher-points-than-you scoring system like Towers in Mobius or the Gauntlet in FEH? If so, I'm not really sure since I haven't played the JP version at all. I do know the game has basically no PvP or co-op but I'm not sure if that's considered the same thing.
