Nice little ideas, but before going anywhere near a game there are so many issues
Ive not fully watched the video just now, but I’ve either seen it before or have seen the Warthog build. (I’m currently sat in a field on 3g where you seem to get rationed access of 5 minutes per turn)
Other than worrying about something even working on the day, and let alone maintaining operator control there’s still safety issues of the equipment crashing on someone, a power line, let alone the delay in visuals from the equipment getting to the operator, their decision time and the commands getting back to the equipment.
We’ve got an RC vehicle delivering pyrotechnics, had a multitude of drones and had a autonomous sentry gun.
For the sentry we would have someone always in charge to kill the system, and a multitude of fail safes.
In 10 years of events, we’ve had eyes on these kinds of equipment, but it’s still going to be a no from me on anything that I could consider safe / reasonably mitigated to put among people
If you want vehicles then there are ways of getting real & mini vehicles into the right types (and scale) of game - all with their own issues, and you can also have ‘simulated’ effects. An example for air strikes is to circle an area with marshalls carrying umbrellas. When the umbrellas go up everyone on the circle is bombed. I have seen players seriously pissed off because they didn’t listen to warnings of other players about the circling umbrella marshalls
