essentially what the title says, the vassal library has a dominion module with all expansions, but it’s all first edition, which is somewhat outdated because it includes removed cards, and doesn’t include cards added in the second edition. Maybe I’m just searching in the wrong place, I just looked in the modules tab of the website, is there anywhere else I could look for that module?
If there’s no 2nd edition, it means that no one has made it yet. Try contacting the creator of the module and ask if they’re planning an update. If not, maybe another module designer will take up the challenge.
