Re: Interact with a bluetooth 3.0 game controller

Probably none because Bluetooth classic is not implemented yet.

Re: RTC battery supply

Does battery have to also connect to VDD3P3_CPU since
VDD3P3_CPU is also the input power supply for CPU
or is it OK to cut power to VDD3P3_CPU but not VDD3P3_RTC?

Re: RTC battery supply

Has an rtc but not a battery-backed rtc. So you have to implement battery switching and sleep/wake in external circuitry and software.

Yes I wonder about that too. Is there any penalty to use the alt address?

Re: PCB (or commercial product) with ESP32 + Power Supply + Relay

Not yet, there are not really any end products shipping yet with esp32 inside that I have seen. Probably itead will do "sonoff pro" or something with esp32 eventually. Olimex board has relays but not AC/DC and not in production yet.
