As I said I have thought of doing one before it would be mostly talking about the development of the game with game test and code editing in the video with me and the other developer talking about the game.
Hype and following behind a project, in addition to monetary compensation, help to motive developers. At least it is a form of motivation for me. The more people have seen the project and commented means that there are more people that want to see it complete.
If anyone is up for sharing some insight, thank you in advance.
As for the status of the Portas Aurora project, I have been working on the economy simulator. However, after a few minutes of writing code I realized that I would need to divide the code into 2 Sims. The first one simulating the economy of planets and a second one encapsulating the first simulating the economy of the player's empire. I hope to have a post about the Economy SIMs in the next 2 days.
I like video blogs because they have more personality to them (and thus offer a better connection to the team.) There are ups and downs though, obviously.
For instance, I never did a video blog because I just don't feel that I have that kind of personality; I'm a quiet person and I don't really know what to say, so I try to write everything down first which makes for a terrible video. I communicate better through text because I can really take my time and I can re-read over and over. My PM, Mikeyo, on the other hand has a great audio personality (video and radio; years of practice) and so we've started doing some video blogs.
In the end, I think it'll come down to the personality of the person that does the video. If it is bad it'll push people away, but if its good it'll definitely help bring in a crowd.
As a side note, if you plan on doing any sort of multiplayer development and shooting videos of testing that (ala a let's play style video) it may be a good idea to start now to get some practice in.
That being said, I don't really watch any video blogs from developers (besides Andrew Russel's now and then) so I'm not sure how much of a following it has.
That's my two cents anyway. Looking forward to hearing about the economy sims!
