Over the past couple months, I've picked up the basics of working with the Photon Fusion package, and is a very powerful tool for individuals like myself or teams looking to put together a scalable networking game.
Even with the free AWS Light Sail plan, I am able to host 12 testers without exceeding the free tier plan, but the option to expand is available.
Prior to this, I was using photon unity networking, which is an older product from Exit Games that served the purpose of peer to peer networking, which was a great introduction to game networking in general. But I can say that Photon Fusion is the way forward once the basics of networking have been picked up.
I don't have the free time to spend on this project, which the next steps are to get better basic animations, models, vfx/sfx, game mode. Should I get the opportunity, that is where I will start.
