Sins of a Solar Empire: Rebellion

I don't think I have ever heard of, much less played, a multiplayer match in this product that did not desync. It doesn't tell you it desyncs, it'll happily march along as the players act out entirely different ♥♥♥♥♥♥♥ realities, but as sure as the setting sun it will desync. It's actually worse than Supreme Commander in this respect, another product I had the misfortune of playing extensive multiplayer matches in - without ever a single one reaching completion in a sensible fashion because the netcode is apparently just that bad. As someone who spent several years modding the project I can attest to the fact it is an utter travesty under the hood and just about everything that could have been done incorrectly was done incorrectly. Their internal tools, like the ConvertXSI utility, are also a disaster and lack any form of proper error handling whatsoever so it's no shock the actual game is a mess. That's before you get into the silly balancing concepts. If your game gets far enough to experience them before it turns into a slideshow from fighters, anyway. Interestingly, the particle effect system in SoaSE is significantly less advanced than that of Warcraft 3, and Blizzard isn't exactly reputable for having modern software in any fashion. On the plus side they didn't use AI for their 2d art like their later product because that avenue of laziness wasn't available to them yet. Shoutout to the good boys that helped my endeavors back in the day. Hopefully you moved on to something less soul destroying.
