Hello guys, i buy trainz 2019 on auran site and i want to play to my steam account but i dont have serial number? who i can add trainz on my steam account?
You can add it as a non steam game to your library. Go to Games, then go down to add non steam game. It'll open a window and you have to find TS2019.exe and click that. You'll also need a different shortcut to launch it via steam.
It actually has some useful features and I can understand adding it. Screen shots and a generous amount of storage for them for example, and the ability to invite friends from it to watch you play it. No harm either way he does it. =)
