First of all - making the 'medical emergency on a crane' require a POI- rather than getting a medical emergency on crane in the middle of a housing estate.
2nd - This may seem silly, but on the 'person hit by train' call, decreasing the number of pumps required to 1 or 2, and increasing the number of Heavy rescue's required, which can vary from 2/3, as in real life, there is a large amount of rescue equipment required for extraction of a casualty from under a train. Pumps are required for calls in real life for the 'pumping equipment they carry, so would not be much use for a rescue like this!
Thirdly - this has been discussed before, and dismissed - but allowing from renaming of missions. The aim is simple, rather than the literal translations from the German game, we can set our own name to missions.
Opinions please
