Simulation game Football Manager, where players take control of the day-to-day running of a football club, is to add new layers of difficultly by asking gamers to deal with the consequences of Brexit.

The game's developers, Sports Interactive, said the vote to leave the EU in June was too significant a development to omit from the game - and so varying degrees of simulated regulations are now being added following discussions with "politicians and people in football".

It will be pushed to players as part of an update to be released in November.

The new feature will see players notified some time between two and 10 years into their in-game career that the negotiations over the UK's withdrawal from the EU were under way, with another update a year later revealing the outcome.

This will range from a "hard Brexit", where work permits would be required for many players, to a "soft Brexit" - where free movement of players remains.

Other scenarios built into the new feature include Scotland choosing to leave the UK after a second independence referendum and remaining in the EU, with Scottish players then also required to gain work permits in the game to play in England.

Sports Interactive's studio director Miles Jacobson told The Telegraph that Football Manager's original plan was to have a single scenario, but soon abandoned the plans because of the complexity of Brexit.

"Of course, none of us know what will happen, it changes on a daily basis," he said.

"Six weeks ago I would have predicted a soft Brexit, but after the Conservative Party conference a hard Brexit is much more likely."

Mr Jacobson added that the various scenarios will have a big impact on Football Manager's gameplay, detailing one simulation where if the same points system currently applied to non-EU based players in need of a work permit was extended to include those within the EU after Brexit, Chelsea's N'Golo Kante and West Ham's Dimitri Payet - two of the Premier League's biggest stars - would not be eligible for to play in England.

"That's two of last season's three best players," he said, adding that some of the new scenarios will make the game "difficult".

Football Manager is known for its high level of detail, with gamers able to manage individual training regimes of their squad, as well as take part in press conferences and oversee staff recruitment across their club.

It has built a large fan base since first launching in 2004, with the average player spending 240 hours a year on the game, the developers said.
