Off topic, but which one out of them 3 is most fun for you,
@Chris Davies ?
For me, 2017, because 2018 (despite little ML additions, such as better transfer fee negotiations) is when the AI starts to shift towards those ping-pong moments and chipped through-balls to bail themselves out of trouble. It's nowhere near as prominent as 2019 (and you can play a deep defensive line to stop it) but you can see its origins (and every team hits those through-balls with the same
unerring accuracy).
Also, I've seen the lowest pass completion rates for the AI in 2017. Usually they're over 80% but I've seen lower on a couple of occasions, which is rare for me with the others.
On the ball the response times let you down sometimes (especially on Superstar where it's SUPER OBVIOUS they just do it to stop you scoring), but it's not 2014-level laggy.
Add to that all the tackles that fly in, and the weight of the ball (better physics than 2018 and better goalkeepers too IMO, they hold onto more), and it's a clear winner for me.
EDIT: Just nipped back to 2018 and, although Ibrahimovic scored a wonderful shot from distance against me, I ended up beating Man United 4-1, with Burnley, scoring four headers, two of them from Aaron Lennon who's about 3ft 2in.
I had an ML that ran for years on 2017, and I've realised now why it is that I haven't done that since. Looking forward to playing it more over the next few weeks.
It must be said, though - the one thing I don't get from any of these games is decent midfield battles. FIFA 17 is great for that (yes, I've been playing retro FIFAs too) - and then they go and spoil it all by giving everyone jelly limbs...
