Various spanners are thrown in the works by the managers in order to make the game more difficult and challenging for the role-player. These include:
- Trains breaking down in the middle of tunnels.
- Trains coming anywhere up to half an hour late, with no explanation or apology.
- Fines for having the wrong ticket/mission card.
- Unhelpful and occasionally abusive "station attendants".
- Poisonous air with little oxygen.
- Rogue commuters who possibly have no ticket/mission cards of their own and who will try to steal from others.
- Other commuters who will make the game unpleasant by sporting various enhancements like smelly food, self-generating body odour as well as chemicals in their heads making it difficult to see out of the windows.
- Ungrateful transit employees going on strike and shutting the place down because they feel they are not paid enough to sit on their butt all day.
A government health watchdog also said that chest and bronchial problems amongst Sydney-Sider had increased ten-fold since the introduction of the game, and recommended that tunnels be cleaned up "to prevent a potential public health catastrophe". CityRail was unavailable for comment as their media spokesman's train had broken down, and their deputy commissioner had been taken to hospital suffering from chest spasms.
Various plans are afoot to make the game even more complicated with the addition of extra routes and mission cards as well as compatibility with a new aspect of the game currently under development called "LightRail". A similar and simpler game exists in Melbourne which may be accessed by use of Metcard Systems - the two parts are known as Connex and Yarra Tram; but as yet commuters are not armed with laser guns.
