Hiya! The name’s Oliver S, and I’m the Project Coordinator of a small project named The Dawn of Twilight.
We recently moved to Unity from HeroEngine, mainly because we’re thinking of incorporating Oculus Rift-support into the game, so we’re kinda new on the Unity scene 
My question would now be, as we’re making a small online role-playing game (not an MMORPG, because it definitely isn’t ‘massive’ 
), is there any server middleware that you’d recommend? Should we build a server from scratch, use Unity Master Server as a base, or should we go with something like SmartFoxServer?
Thanks in advance for your time
Hi,
since no one replied, I thought I’d chime in.
From my signature you might imagine what I would recommend but the reality is that it really depends on the requirements of your game.
If you’re looking for massive scalability then yes, you will probably need to look into third party middlewares that can handle very large scale projects.
Also you should take a look at the options offered in terms of security, administration and monitoring which are an integral part of any MMO game.
As regards Oculus-Rift, there’s not much to worry about, but hey… cool!
Since you just joined … there was a pretty active thread with networking solutions:
http://forum.unity3d.com/threads/95277-Networking-Server-Comparison-Chart
It is not very active anymore - but at least you get an overview what is out there.

Sorry for the delay on my part
I feel the question has been answered, so thanks to everyone who answered! This will help me a lot!
Hey Lapo! didnt know you were over here 
If you require scalability, you will have to go beyond the built-in networking.
If you are not needing server-side physics, either SmartFox or Photon would be good (im using SF)
If you ARE needing 1:1 server-physics, then you will need to go with uLink, as the server can run as a Unity client (will require a sizeable amount of coin to really get the most out of it though)
As for the comparison chart, some information is fairly outdated, but still has good information to help you make your choice.
