Hi everyone, I’m trying to understand what “skill” really means in 0 A.D. Ratings are often used to "balance" teams in group games, so I’d like to know what abilities actually correspond to each rating. I’d like to know how you associate abilities with Elo ranges. For example: 1100–1200: What basics does a player handle well? 1300–1400: What additional skills or strategies have they added? 1500–1600: What have they perfected compared to lower ratings? 1700+: What makes a top-tier player stand out in terms of abilities? The idea is to get a clearer picture of what each rating represents in practice, not just the number of win/losses. Thanks for sharing your experience!

STUN is now always enabled.   You can try enabling UPnP on your router or manually configuring a port forwarding. There are a bunch of guides on the internet about how to do so, how exactly depends on the model of your router. There's also a section in the FAQ about it: https://gitea.wildfiregames.com/0ad/0ad/wiki/FAQ#how-to-do-port-forwarding

Last time that happened to me it was a very little detail in my router config after my internet provider made some work in the area

For the next version you should package it with the game's archive builder.  Since you're on github you can automate by adapting this action https://github.com/0ADMods/ponies-ascendant/blob/master/.github/workflows/ponies-ascendant.yml
