I'm surprised it took this long as well
I made this with Adobe Premier Pro & After Effects CC 2018. All the 3D models were purchased by me (a few years ago), not the best quality, and definitely not designed for game engines. Our 3D models (game models) would have to be re-skinned in After Effects.
The premise of the scene - creating a fun hobby/briefing room environment.
XOOM pre-recorded his narrative via green screen
while I set up the scene in After Effects...
Added the Power Point presentation, video clips, and tweek 3D camera movement a bit and PRESTO!
It was a long few weeks, but I had a blast putting it all together.
*Fun note* It took 6 hours to render the final video
