What are the pros and cons of available network solutions/assets

[EDIT 04/04/23] WARNING: This list hasn't been updated in a few years so a lot of information is missing and outdated.

Here's a link to a similar google doc where you can get more information on some of the solutions listed here, and general networking terms: https://docs.google.com/document/d/1ufcl6_ylbzthfmzzZ7HPiwDLR0sr1N3UAunUG9r…

Take some time to explore their websites, skim through their documentation and examples and you will find the best solution for your needs. Multiplayer is a complex matter which requires dedication before, during and after the coding part.
