Yes, I know what you feel. Playing FGO is also hard for me (especially with their gacha system). But, satisfaction from maximizing your Servant or CE, clearing story and event, got their reward, it feels so good.
You can read the manga, just search Fate Grand Order manga or the most straightforward way to understand the story is to play the game but it is understandable if you cannot do that.
