Hi,
To be honest, it's a bit quiet in the ROSE world these days. Private servers with big intentions come and go from time to time but nobody seems to make anything stick. There are a few "official" servers running across the world with the North American version being the only English version (
http://roseonlinegame.com/). AruaROSE has been running for long enough that I guess you can bucket it into the "official" category now (
https://www.aruarose.com/). These servers manage to chug along but I don't think any particularly evolutionary or exciting has come out of them in a long time.
In the private dev side the main osROSE server projects have stagnated. I think one of the evo servers (maybe the RoseZA version?) is the most developed. PurpleYouko's project 137 (
viewforum.php?f=58) is probably the most comprehensive in terms of functionality and is probably the only project that includes client source code. Raven and L3nn0x have been consistently working on a re-vamp of the osIROSE server which has gotten pretty far in infrastructure but is missing a lot of gameplay elements (
https://github.com/dev-osrose/osIROSE-new).
Besides that, if there is anyone else working on ROSE projects then they are working in secret/in a silo but I think it's more likely that there isn't many other people active. There's been a couple of posts by AnimalCrackerz who seems to play around on the art side of things, he might be working for a server or something. I myself have been bouncing around between various client development initiatives but nothing has stuck for me so far.
If you're looking for an iROSE revival, I don't think it will happen anytime soon. However, I think there are enough people around that these projects might have a heartbeat for a little while longer.
