I think that those reviews as the ones on Steam are very much dependent on personal expectations. Dozens of indie-beta games on Steam get ratings of 80% and more although they are barely playable, while an in my opinion good (surely not perfect) beta version of FM15 gets a - fairly - low rating. - Why? Because people expect every new FM to be the best and most revolutionary FM of all time - which isn't realistically achievable. Compared to most other games available - especially simulation games - EVERY FM is concerning its content and the quality of the latter extremely well made, which in my opinion is the main reason why both 'professional' reviewers and gamers on Steam rate FM15 fairly badly - the general standard is just too high to revolutionize the game every time a new version comes out.
