Because the actual Steam achievements are largely a load of shite.
"Your team hasn't conceded in 30 matches"
Has anyone, EVER, gone 30 matches without conceding? I can't imagine that's ever been achieved.
Hopefully, we can come up with better. Ideally, I'm looking at about 50 different accomplishments, ranging from the fairly simple (score five goals in a game) to the far harder (win each of the continental competitions).
The more that could be achieved in the same save, the better, but this isn't a deal breaker.
Hi guys, it was myself that wrote this post and made up my own achievements. Like yourself I hate the steam ones and wanted a decent set that was tailored to my own specific save. I have also happened to get 9 other people ask to join in so it's made it more a challenge in a challenge now!
I'm more than happy to send you over the spreadsheet of what achievement I've set if you wanted to see them and tweak them to suit yourself
