Very valid points, all seconded.
It still remains to be seen if DTG really 'opens up' the game for the casual creator, as originally intended.
3D modeling and texturing aka content creation, even route editing using prebuilt supplied assets, will it be limited to their 'preferred business partners'?
They are currently working on adapting the UE4 standard editor to their specific needs.
But will it ever be truely WYSIWYG? Will it have sufficient documentation for the non-professional content creator?
When you are inclined to content creating, DTG advises you to start learning UE4, and there is plenty of material available.
And in the larger scope of things? What are DTG's long term intentions with TSW apart from many promises made earlier?
A locomotive/train control type of game to compete on the console market, or a true rail transportation simulation?
The same as TS2018/9 but with a nicer picture? Possible VR and multiplayer to attract the upper market?
Time will tell ...
In the meantime, cash needs to flow ..
