Your projects look interesting, but I'd like to watch a small video before downloading 300MB of stuff. :-D
A space simulation sandbox similar to KSP · By
What i usually do is record an interesting gameplay session, then choose clips from that and make an edit of about 1 minute, better if on beat with the soundtrack.
Finally add title at the beginning, CTA and credits at the end. :-D
This is an animatic for a project i'm working on, it's all placeholders, but music and visuals match quite good: https://vimeo.com/user413421
Enjoy!
