I had a dabble with MyClub (really want to call it something else but don't want to get told off by the mods) during PES 18, and I actually enjoyed the development side of things, taking Brewster as a 52 OVR and training him up to become this high rated superb CF, but the main downside to the mode was people. playing against actual people who's only intention was to win at all costs and piss you off as much as they can in the process, was a chore.
I've seen a few MyClub vids on Twitter, and its like watching clones playing eachother, every team having Messi, CR7, Neymar, De Ligts, Van Dijk, Salah etc. using PA3, direct ping pong pass skill shoot, Where is the fun in that?
It's not for me.
