Not magical - just not as ****-fancy and power-advertised as all the servers here, as that leads to toxic spoiled kids infesting the community.
As I said - mature player basis and a reliable server which won't go down just like that.
Everything else, about the concept etc can be found here:
I'm NOT afiliated with NGESRO at all - just playing there and enjoying the get-togethers that people discuss on discord.
-- edit --
Let's please not start a flaming discussion of waht server is the best and blablabla. I'm jsut giving my opinion as mature person on this board, and I don't feel like starting a server war.
I work, I take care of my wife + Kids, I enjoy some free time once in a while during the night where I can freely log on the server, chat a little bit with folks, and maybe do the one or other trade with them. No rushing, no bashing, no competition of who has the bigger e-*****. Just enjoying some oldschool SRO after a stressful day

And what gets me the most, is the simple thing that even IF I search for it -> I can NOT find any hint of "Donate Moneyz to get kral advantages on our server".
NO DONATIONS, NO SHOP - PERIOD!
