As a few examples will be more helpful than a wall of text, I imagine something like the Nexus mods or the Steam Workshop, but implemented and operated by Factorio dev team.
I imagine some place with a search engine where modders could publish their work, a few categories to make browsing easier, and fully integrated to the game's current mod manager.
While searching, I have found two attempts to "centralize" information about mods :
a player that offered to host a Mod repository : https://forums.factorio.com/forum/vie ... =34&t=7635
The wiki mod list I found linked in this post : https://forums.factorio.com/forum/vie ... =14&t=7526
Both of them seem bound to fail in my opinion, because they need people who are not directly concerned to keep information up-to-date. Moreover, a forum does not have the optimal structure for a huge mod base. It's okay for a few mods, but past one point, it becomes really messy.
I see two possibilities : wait for Steam, and rely on Steam Workshop, or host a proprietary mod repository.
- Steam Workshop would allow to have a working solution with little to no investment. It exists, it works, people use it. BUT (and this is a big but ) it will be a major problem for all non-steam using Factorio players, and I feel there are many people who are not on Steam.
- A repository owned and operated by Wube software would have the exact opposite advantages and disadvantages : it needs investment, in time and money to set-up and to run, but it would guarantee all Factorio players to have access to it. Moreover, I'm sure that some community-fans would be happy to help keeping things tidy like this forum's moderated by passionate fans, just because this game deserves it.
