Simulation games tend to endure very short spells of popularity but Football Manager has dominated sales charts for years now. Combining football with numbers and stats seems to be a winning formula - it's a game that people simply cannot get enough of. For good reason too. The series has an amazingly addictive nature; once a team is set up tactically and personnel-wise, the real fun is seeing how they perform on the pitch week-in, week-out, before fiddling about to try and paper over any issues. With most sports games, the yearly release simply serves as a roster update, recreating real-life transfers and movements to give players the most up-to-date squads possible. New features are added on a yearly basis too and the in-game match engine is constantly being tweaked to make it as realistic as possible. These might seem like superfluous changes but Football Manager is a series which prides itself on realism; after all, it wouldn't be a very good simulation if it was unrealistic. The series is becoming more and more immersive too, recreating the excitement of real-life events like Transfer Deadline Day to hook players into it's world - vital features which make the yearly updates worthwhile. Impressively, despite each game only having a lifespan of a year, fans manage to pour hundreds of hours into one Football Manager career - that level of dedication is simply unheard of in other game series and it's why Football Manager will be released until the end of time.
