The thing about FGO players like me is that we all enjoy and stick to the game, but we don't recommend it to anyone.
It isn't about gatekeeping, it's a genuine advice, the gameplay is decent but isn't as good as any current games, the gacha suck ass, genuinely the worst gacha system ever created
I saw multiple times this same logic (or sometimes as a dark humor self-mockery thing) : I play it but i will never recommend it to my friends
One most recurring reason being :
"If you buy the DLCs for the full experience, i calculated it and the number was so big that i would feel guilty to recommend it to my friends."
