Unity has updated their DOTS Samples repository with two new documents: "Misconceptions about DOTS and Entities" and a performance checklist. They are a great read and a first step towards undoing the misunderstandings DOTS caused. Find them linked in the ReadMe here: github.com/Unity-Techno...

While I likely won't have the time to play Stronghold DE, I continue to be impressed by Firefly's community messaging. Many studios could learn from their approach. Open, direct, to the point, honest. Just good!

@jeremy.laumon.name I recall that you said only use {ptr, length} strings without terminating zeroes. How do you deal with calling Win32 APIs? Always make a temp copy? I've thought about adding a check first to see whether the string is already null-terminated, but then you might read invalid memory
