Yesterday, I uploaded a Victoria 3 mod to the steam workshop entitled "All Achievements Instantly as Prussia Mod". As outlined in this dev diary: https://forum.paradoxplaza.com/forum/developer-diary/victoria-3-dev-diary-55-achievements.1538861/ it was decided that the restrictions on mods, checksum and ironman should be removed from achievements for Victoria 3. They implemented this in the game as described, and any mod can make achievements easier, or harder. They can do this directly, by changing the code of achievements as I did, or indirectly by making other aspects of the game easier. If there is a rule about tampering with the code of achievements in mods, I haven't ever seen it.

I happened to make a mod that made achievements very easy, but if there is a line to be drawn here, where is it? Any mod that makes the game easier, of which there are many on the steam workshop right now, therefore also make achievements easier. If there is a line, or a rule, about the effects mods have on the difficulty/accessibility of achievements, what is it?

It was highlighted during the development of Victoria 3 that the game would be very open to modding, and a whole dev diary was written explaining how to make mods for Victoria 3 and it also highlighted the variety of mods created for past paradox games, from very minor changes (like my mod) to huge overhauls.

Therefore, a mod that instantly unlocks all of the achievements is completely in line with Victoria 3. It is a logical and clear conclusion of decisions made about the game, even if you dislike it, or resent the fact I made it, or agree with those development decisions. Those choices for Victoria 3 completely opened the door to the mod I created.

No reason was provided to me for why this mod was banned. If you won't overturn the decision, I would at least like a proper explanation.
