Thanks to pampaliny from trainsim.cz, let us can release our creation. Since TSW4 PC editor was still not in completion, the release of full version of PC editor(not beta) would in a far future. There may be a new TSW.May be not. Every content creators, would you let me know if you gonna release and maintain your route / loco / timetable / skin / sound mods on TSW4.
Considering old DLCs work with the New releases, and if the editor is updated regularly upon each release. Then yes, I'd support my mod as long as my mood and time allows for it.
