Someone on steam said they were playing on version 1.3.7, which is the last version before the engine update and all the new DLC. Is it possible to rollback to that update still?
It is possible using Galaxy to roll back to version 1.37 You open the gamecard in Galaxy, then use the menu just to the right of the Play button at the top of the screen. Select Configure from the menu, then uncheck the option to keep the game up to date. From there, you can select any version from 1.37 up to the current version. Note you will lose access to the HD updates and the DLC past Pirates of the Flying Fortress.
On the other hand, it allows you to install the excellent WorldsMerge mod which stitches the original eleven multiplayer maps (with canges made so that they can be played solo), the Pirates DLC and the main game into one total game and adds a ton of content to the game of varying quality. The install process is involved, but is worth it in the end, in my opinion. I need to set it up again for a new playthrough, heh.

Hope this helps. =)
Thank you very much, that's actually what I wanted to do lol. Try worldmerge, and have future vanilla playthroughs be untainted by anything post-2017
