This need to be part of official Unreal documentation. Thank you!

[greyly_]

I'm currently slogging my way through many hours of Epic's training videos and it's very refreshing to watch something like this which has actual effort put into it. Not to mention editing.

Best overview of Unreal replication on the internet.

I've probably seen thousands of tutorials about anything in the past 10 years. However, I've rarely seen this level of quality in any of them. Top notch, really outstanding! Thanks a lot for this!

[ChinyONE]

This level of perfecion is unmatched. U could easily make a good amount of money with this level of quality :D. Super nice to put this up for free. THY SIR!

[LevySkulk]

Extremely useful video. So hard to find videos that are willing to break down some of these design philosophies and de-mystify documentation. After watching a few times, I feel confident diving into the documentation myself.

Edit: Two weeks later and I'm watching this video for the 4th time.

Edit: It's been 7 months and I'm back. This shit's deceptively simple to understand but quite hard to put into practice.

Edit: 9 months and I still come back to this video sometimes. At first i was coming to learn how to to this with Blueprints and advanced sessions, but now I'm here for C++ and workflow lol

Alex your content is SO GOOD, you have to apply for an Epic grant or something.

Best video on Multiplayer in Unreal Engine. Amazing animations + diagrams and love the fact that you show the c++ part as well and not just BPs.

[DaniArkadia]

I've rewatched this 10 times over the last few days in order to soak up all the details. This is so valuable thank you!

[marv]

Oh man after more then 2 years of trying to understand UE4 multiplayer i finally found your video. 10/10 <3 feel hugged man i needed this!

[delvik]

You're saving me so much time and broadening my understanding at the same time, every time I watch this.
Thank you so much!

[beaubilyeu]

Seldom one to get involved on YouTube comments, but this is pretty excellent. Concise, informative, and well narrated.

[thepolyglotprogrammer]

I try to come back to this video at least once every 6 months as a refresher. So good!

[netdawgx]

This video may win the award for most informative (and best produced for teaching) video of all time.

I agree with the top comment -> this *needs* to be a part of the official Unreal documentation.
I'm sharing this with everyone.

[TheWolfcast]

Thank you for this video, I have been trying to find a resource for a high level understanding of networking in Unreal. This was very concise and most everything made sense to me!

[jonsnow]

Dude! You’re videos are bloody brilliant! I learned more in 20 mins than most 5-10 hour video courses. You gotta do one on GameplayAbilitySystem

[simonfinnie]

This video is excellent. You explain everything so efficiently while remaining incredibly clear and highly detailed.

[Raidoton]

This video gave me the confidence to give a simple turn-based multiplayer game another try.

[Alander]

Please dont stop with making those valuable videos, this is just pure gold!

[spectator]

Thanks for this. I appreciate the high information bandwidth; it was great to hear someone speaking with the voice of an experienced developer, rather than the endless newbie UE4 videos that are so prevalent on youtube.
