MMO style server tools

So I have come up with a concept for a game I would like to attempt to create. that has the potential
to be huge however as a solo dev with only a small amount of experience I’m aiming small to start with, however I would like to start with a reasonable code base that has the potential to scale if required.

I’m sure some of you will read this and want to post “don’t do it, its to hard” as soon as you see MMO, however the current scale for this project is the current scale I’m looking at is ~10 players simultaneously in a single location however the world lore I have written allows for expansion beyond this first area so I would like to get my tool selection right the first time rather then have to retool if i decide I want to make more of the project once the initial goals are met.

I am currently looking at tools like UMA and atavism to use as a potential starting point for the project. can anyone recommend any other items that might be useful to look at for this type of project?

also, I’m sure someone will want to say “don’t make an MMO its to hard” and your probably right, however I want to try and make my game the way I have envisaged it, even if it never gets past being run on my pc for testing, and yes I’m willing to spend the money just to reach that goal.

I guess first things first… What Languages do you know? C#? Java? C++? Python? Atavism’s Server side is all coded in Java and Python while the Client is in C# So if your not good at Java I would advise finding something that is in a language you know. Don’t just look for tools that do specific things but look for tools that you can actually work with.

Well i dont know your skill level, but maybe you could look at frameworks like Photon Server (not PUN) or uLink?

most of my programming training has been in java, however I also have some experience in C#, and C++ among other languages.

Ill take a look at Photon server.
