Just to add to the convo here's what the Japanese side of Sega said for their server closure announcement (make this what you will):
I am Sakai, the producer of "Phantasy Star Universe Ambitions of the Illuminus" (hereafter "PSU").
I have some sad news news.
We'd like to announce the end of service of "Phantasy Star Universe Ambitions of the Illuminus" today.
■ Notice of termination of "Phantasy Star Universe Ambitions of the Illuminus"

Six years have passed since the service started in 2006.
At the beginning of PSU, we had some really big trouble and had to deal with it.
The development blog that we started was unable to update satisfactorily and ended up ending.
We couldn't do anything at that time, and as a result everyone was greatly disappointed, and it was some stressful times for us.
About a year later, "Ambitions of the Illuminus" was released. However, it wasn't a big hit, and I couldn't release the new additional disc that was planned, so episode 3 was only delivered in story missions in network mode.
"Pantasy Star", which was compromised by "PSU", came back to life with the blockbuster "Phantasy Star Portable" that was a spin-off. This was followed up with "Phantasy Star ZERO", "Phantasy Star Portable 2" and "Phantasy Star Portable 2 Infinity".
The experience of those staff members is alive in PSO2.
Without "PSO" not only would not have gotten "PSU", but we wouldn't have the successful Portable series nor would "PSO2" be created.
With the success of the Portable Series, you can now pay for options, introduce free courses, and get new updates.
Although option billing and introduction of free courses were tough choices in difficult circumstances, it is also true that subsequent operations became possible.
It is now possible to add new fields based on the portable series and new original costumes.
It's been six years that I wouldn't say has gone well, but nonetheless I've been able to run it for the past six years thanks to the players who loved and supported PSU, despite the trouble. Hmm.
I have never forgotten about PSU.
We have made it over our own lives. I think we did our best in these 6 years because of the regrettable experience at that time.
Thank you to everyone who loved PSU.
After August 30, the premium course will be free of charge, so it will be a short while until the service ends, but I hope you can enjoy it.
The operation of "PSO" has ended, and now the operation of "PSU" is about to end.
However, the essence, spirit, and experience are definitely passed down to PSO2.
"PSO2" has just begun.
The server is also on the verge of stability.
Updates are coming soon, and a lot of fun is waiting.
Online games are growing games. Based on everyone's opinions, we will change to a more interesting and comfortable environment and increase the volume.
We will continue to respond to the opinions we receive from all of you, and we will continue to do our best to make even more people enjoy the online game by making better “PSO2”. I would like to come.
I'm really thankful to you.
And thank you for your continued support of the Phantasy Star Series.
Excuse poor wording in some parts, you all know how Google Translate can be. I regardless did my best in some areas to make it sound better in English.
