A new simulator called Train Life to be released at the end of August. https://store.steampowered.com/app/1330660/Train_Life_A_Railway_Simulator/ Later this year Sim Rail will hit the tracks too. https://store.steampowered.com/app/1422130/SimRail_2021__The_Railway_Simulator/ Also later this year Trans Siberian Railway Simulation will also ride the tracks https://store.steampowered.com/app/998400/TransSiberian_Railway_Simulator/ Plenty of competition now for DTG. I am sure DTG will rise and better anything else on the market.
Have you been hallucinating again? Seriously, the Trans Siberian Railway simulator looks fun, but I think it will be a while before DTG include 'killing wolves with chainsaw' and 'drunk loco driver' expansion modules.
