The bus with his special announcement system is initially very complicated.
From "Starting and start right away" can be no question here.
However, a very detailed manual is in the process which makes good reading.
This most questions are answered and you're set.
If you descend a few laps, understood as the public address system as well as the pitfalls of the route.
In reality, no bus driver fell from the sky.
Currently there are still some bugs, so works as the heating of the bus is not correct.
But this, it will soon provide an update.
The developers are the official OMSI-Forum active, there are several specific issues for AddOn.
The contact is very good, it will react fast and friendly.
Of course, the big OMSI community help with questions or problems.
I myself have never been to Vienna, all the way makes me but a very realistic impression.
In particular, the specially made objects and roads, you do not know of any 0815-OMSI card stand out.
Original announcements, AI road and subway passengers with Austrian dialect, much more. complete the experience.
In future repaints and mods can be expected for other OMSI buses, with which one can make Vienna uncertain also, provided that the LU200 one does not suit you.
From me there is a strong buy recommendation.
