Hey there,
i've been following the progress of Fernbus for quite a while and i have to admit, at the start i didnt really like it due to previous TML games where they had good ideas, but there was some things it lacked/was bugged. But after more screenshots and the trailer was released i began to change my mind. It's great to see more bus sims being made, and i hope this will be a really sucessful one and will have a long support for it.
Gotta say, i love the trailer song 
I read that there wont be multiplayer support at the start, but i hope that in the near future there will eventually be multiplayer support. Many simulation games kind of lack this support and it'd be great to go on coach trips with friends aswell as the public.
Hearing about the buses will be customizable with free DLCs, for example interior decoration, etc. sounds great, I know Euro Truck Simulator 2 has this and it'd be great to have "Coachy" decorations for Fernbus.
It amazes me how steam can turn 45 GB download into a 3 GB download.
Good luck to the team and cant wait till the 25th to play this!
