My 4000+ words thesis on FIFA 18 was published at Digitally Downloaded here.
There are several reasons for the review's length "problem". Firstly, unlike most FIFA reviews, this was not an incremental one (of the "what has changed since last year" type). Secondly, there are so many modes and options in this game that a review ignoring some or most would potentially do the game injustice or at least leave its reviewer open to flank attacks along the lines of the "how can you criticise the game when you haven't tried X?"
Thirdly, and most importantly for me, is the fact I have a long history with FIFA. FIFA, my closest friends and I went a long way together, and no matter what I will always hold this video game series in high regard.
