FM will be the same every year. Full of bugs until the 3rd patch. The real question is whether you prefer the more polished version from the previous year or if you are happy to play through the bugs until that 3rd patch around Feb/March.
I'm back on 2013 but for every release, I have always said "I'm not buying it this year until 3rd patch" but then I end up buying it and being disappointed so really I can't complain, I knew I shouldn't have bought it this early but I know SI will come good eventually and I want to support them...
