Depending on what games you prefer, you could try the following
in order to avoid an installation of "Windows":

a) run the games with wine (I'm doing this, actually)

b) create a VM and run "Windows" games inside that

If both do _not_ provide a sufficient environment for your
games, you probably need to install it on your hard disk.

Correct. You should therefore first install "Windows" and
then FreeBSD. If you have installed FreeBSD previously,
you need to boot from a live CD or USB stick and repair
the damaged MBR, and also install the boot manager so
you can select to boot the OS or "Windows".

Yes, because it's less trouble. :-)

Boot from a different media and repair what "Windows"
has damaged.
