The "No Journey, Man" challenge

[McBride]

This can take the basic rules of the journeyman (start with no reputation or coaching badges and work your way up the ladder, all the way to the top league, winning that as well as regional and international cups available) but you confine your journey to a single city. You spend your entire footballing career living in the same home. Because of the specificity of this instead of starting unemployed (which is one of the journeyman rules) just pick a team at the lowest wrung from your chosen city and make yourself manager. After that you must apply for and be hired for every other move.

The city you choose should have to have a number of clubs spread throughout the levels of their league system

The simplest and most abundant in FM would probably be London which has 20 teams in the game.

Prem - Arsenal, Chelsea, Crystal Palace, Fulham, Tottenham, West Ham  Champ - Brentford, Millwall, Queens Park Rangers L1 - AFC Wimbledon, Charlton Athletic L2 - Leyton Orient NL - Barnet, Bromley, Dagenham & Redbridge, Sutton United, Wealdstone NLS - Dulwich Hamlet, Hampton & Richmond Borough, Welling United

When customized lower leagues show up this will be even easier because there will be more clubs to choose from but harder because most of those clubs will be in the lower non league divisions but for now you could also expand the city to a county or region to increase the amount of clubs. For instance, Greater Manchester has 10 clubs in the game right now. Paris has 4 .
