The EU4 devs have been using forum suggestions to aid gaps in AI development

The developers at Paradox Tinto - the Barcelona-based studio that's dedicated to supporting Europa Universalis IV - are hard at work on the next round of content updates for the grand strategy game. The studio has also been trying to staff up so that there is dedicated support for tackling every aspect of the game's design, especially the AI.

Studio manager Johan Andersson tells us that his team only recently welcomed an AI programmer to keep working on the game's complex coding, and one key part of bringing staff members up to speed was suggestions from the community themselves.

"There was basically not much knowledge left about how the AI code worked because there had been so much turnover on the EUIV team," Andersson explains. An example of this community-sourced knowledge can be found in the most recent dev diary for the game, which gives special thanks to several members of the fanbase. One of the major fixes to AI behaviour coming in patch 1.32 was suggested by a forum user named Tempscire. The dedication reads: "A special shoutout to Tempscire, whose reverse engineering of AI army behaviour is somehow easier to understand than the code itself."
