After 13 years of playing manager games, I have to say that Progression Football is the best one out there.
It is the first game when you actually have to make choices, not play a guy for 5 seasons and guarantee he will be godlike.
The best quality is realism. The uncertainty about the draft, the “bets” you have to make on specific players, the chemistry on the team, the fit between players and coaches are only a few of the qualities PFL is offering.
You do not have to devote a lot of your time and you can also join any number of leagues you want. I also love that the seasons are short, 30 days each, so you do not have to wait 9 months before your rebuilted team is actually good.
Moreover, PFL has a very helpful and active community which can assist with any problem and answer questions, not to mention that the creator always listens to ideas and feedback.
In my opinion this is what is making PFL special. It is not a company triyng to lure people for the money. It is a football enthusiast who wanted to create a great Football Manager game and he was/is willing to pay for server costs out of his own pocket to keep the game running.
To be honest I could keep going on and on, but to sum up, you do not want to miss the best GM game on the internet, and BELIEVE ME, I tried them all.
