I think what a lot of people, especially in here, fail to realise is they're good at the game. They've been playing for years, across multiple versions, and sometimes even decades. If not that could have thousands of hours in one or two versions. You are bordering on experts in the game. Of course people like this will find things easier, that's why—like with other sandbox games I play—you have to set yourself challlenges and limitations. Only signing players of a certain nation, only using your youth intakes, only taking people from your scouting reports and not using real world knowledge, or knowledge from wonderkid lists.
A few years ago my uncle, in his fifties, asked me about playing FM. He'd never played it before. Now the man is an expert at football, extremely knowledgeable, and will watch literally every match he can. He's not the type to only watch the games of the team he supports. I think his real world football knowledge would translate well to the fundamentals of FM. But a few years ago the game was terrible at introducing entirely new players to the intricacies of how to actually play the game. I think Sports Interactive knew this as well, and for those past few years there's been a focus on helping people learn the game within the game.
Those years ago I could only recommend FM to students, the unemployed and the retired. You needed so much time to simply learn how to play the game. Now it's a lot more streamlined and if my uncle mentioned it again I'd tell him to pick up this year's version. But the game does have to cater to those people. The people new to the game, who won't use downloaded tactics and don't know there's wonderkid lists out there. If you find the game too easy think about how knowledgeable you are of football or how long you've played the game, even what team you chose to manage and what restrictions you set yourself (and, of course, if you're looking at other people's success they might not be telling the whole truth.)
