After taking Unity Part 4 Game Server and 7MMO Content Implementation, it might be good to take this lecture. For C++ Part 4 Game Server and Part 5 Unreal IOCP integration, while taught in detail, the content is very deep. First-time students might struggle to keep up until the mid-point and then lose interest, I believe. However, if you want to build skills through enjoyable development, similar to Unity Part 4 and 7, then this lecture is also a good choice. On a side note, Unreal's RPC method, designed for multiplayer games, is quite good. And as Unity is similarly pushing its UGS plugin, I think it's great to see them increasingly compete and evolve.
