What?
ModCon is an annual-ish event where fresh trailers and engaging presentations for all the mods of CK3 (and Vic3 and Imperator: Rome) are streamed on YouTube together, as a part of a show celebrating modding and collecting money for charity. And now, applications are open! Everyone can sign up their mod for ModCon 4 (or IV, (or 亖, (or ೪))); which will happen in June 2025! You have five months to sign up, finish that mod and make a kick-ass trailer - or other kind of video related to one mods, or modding itself!

What to submit?
There's three major categories, but a lot of freedom inside them:
- Trailers; showy, flashy, intriguing videos. Shorter than 5 minutes but teasing enough to provoke more discourse than that.
- Presentations; longer, engaging videos. They can be cinematographic showcases, discussion panels about just about anything (we've had a great Modder-PDX Dev discussion last year), or anything else that's long-form and related to modding.
- Events; anything that doesn't fit into the mould of a prerecorded video. Want to do a live Kahoot with the audience? A guided playthrough where the host solves a riddle in your mod? The ModJam - crunching a mod together in the one weekend? All bets are off! (but we'll help you organise it).
I still have questions!
First of all, join the Discord server! In it, check the #faq channel and the rules under the application threads. If you have any other questions, feel free to reply in this thread, or ping someone from the Organization Team in the server.
