Run 32-bit apps in Catalina - possible?

Some games weren’t updated to 64 bit to work in Catalina. Can you run 32-bit apps in Catalina, and if not, how to go back to Mojave? Otherwise, I am stuck with not just gaming apps but with other programs as well.

I would advice a virtual machine rather than wipe the whole thing and restart it again, such as VMware would do the job!
