Sorry, I actually missed it
Currently, no, you can't switch to Sirius. It was only possible to broadcast theGen4 Spice at half-time.
---------------------------------------------
So let's get to the heart of thematter.
ds Nexus got a higher speed factor - so far everything is ok. the players from Nexus and Retro could also choose where they wanted to switch - also ok. But players from the Sirius were excluded, which is also understandable somewhere due to the configuration, after all, you can do research faster in Sirius than on any other server and there would certainly have been complaints, sometimes rightly so. But that'sjust the point, the Sirius players just didn't have an option and at the same time took the server because of the speed factor, which was unique at the time. If a completely new server had been created where everything would have been at 3x or 5x speed from the beginning, I don't think anyone would have complained. But in the Nexus, the speed was subsequently increased to distinguish it from the retro. If you mainly played Sirius because of the higher speed, you look a bit stupid in the tube, because there is now a faster server where you would have to start at 0 and at the same time you have the possibly thick acc in Sirius for which you might have to work hard.
Of course, I'm talking from my point of view, they also share a few players, and I'm into speed. Speed universities with high speed are unfortunately too rare, so every server with more than normal speed is just "nice".
