After a little bit of research as Ben described at the end of the video, here are my notes:
It looks like there are four different kinds of movement that the controls have to handle: (1) moving the tank back and forth, (2) turning it, and (3) rotating the turret independent of the tank and (4) raising/lowering it.
About #4, I did learn that the M1 Abrams has some electric motors that stabilize its turret as the tank is going up and downhill. Maybe that’s beyond the scope of this tutorial, but I thought I’d share it.
Finally, about features, it looks like World of Tanks just has a percentage system for health, and I assume damage isn’t broken down by part of the tank.
(Have to admit I haven’t played World of Tanks as of writing these notes. Downloading the engine was rough on a 1.5Mbps connection, but 11GB is gonna take a while )
