The interesting question would be if DTG adds some a.i traffic to the current "main spessart bahn", or if they might even connect them? If the time period matches, i see it as a "must do". Fact if this company just continue with approach 0815 a-b, and come up with next surprises in tsw5, together with the bigger surprise of the new introduced bugs, its just not enough for me. Ill see my self buying JTs route full price and by the end of the year ill go with win10 and setup a new rig. So my money for tsw will definetly spent 99% on sales, except i see devs have gone the extra mile big time. And this means not begging for rain effects.
It's not called msb extended. It is a new dlc. They can't merge them and be able to create a dynamic timetable which is one of the reasons why mergers can't happen.
