I have RT and the subsequent Class 182 add-on, I was just wondering if you need to complete all 127 services to be able to unlock the German Legend trophy or if it's just to complete the RT silver talent 2 services only to get the trophy? The achievement just states to complete all available services on RT.
If you start with 0/64 services completed then you need to do 64/64 services. Installing the 182 means more work has to be done for the achievement/trophy. It is said to be buggy and not unlock always, though.
