Overall I’m very happy with the way the game is. I think a few things that could be improved are:
A ticket system for reporting bugs, that people can also use to request new features and vote on them.
Subsidies, ala TTDX.
Purchasing exclusice transport rights.
Click and forget upgrading of vehicles on a line.
Setting a splay on the lines. If I start a new line I have to manually create vehicles one at a time with a 1 minute gap to get them staggered, otherwise I get 4 trucks forming a convoy and long wait time for goods to move.
