I’d love to see optional achievements or “side quests” that reward memorable, rare, or chaotic moments in games with cosmetics, titles, coins, or profile flair. Catan naturally creates hilarious and unlikely situations over hundreds of matches, and it could be fun to celebrate them with things like building a 15-length road, holding all 19 of one resource, winning without Largest Army/Longest Road, getting robbed repeatedly, or surviving terrible luck. Even “bad luck” achievements could make frustrating games more entertaining and memorable. I think it would add a fun layer of long-term progression and storytelling beyond just climbing ranked.
