I upgraded a 20.10 system with steam already installed, and then tried a few games that worked:
Proton:
Hellblade: Senua’s Sacrifice
A Plague Tale: Innocence
Dirt Rally 2.0
32 bit native
Saints Row 2
Victor Vran
64bit Native
Dirt Rally
And a 32bit that did not work:
Shadowrun Returns
But that does not run on another 20.10 system either, while it works on a 20.04, so I do not think its about the packaging, but something else(ldd shows all libraries available). ppa-purging the ppa did not make it run either.

Edit: I used my steam controller both from the normal steam window and from big picture without problems.
I also could opt into the Steam beta and out again.
And for purging I used ppa-purge instead of sudo apt-add-repository -r which then installed the steam package from the hirsute repository.

PPA purged successfully
package for inclusion in Hirsute Hippo. It’s mostly a merge from the package in Debian Sid with some slight modifications.
Everything looks positive from a packaging perspective. We’ll look at uploading this update to hirsute, with the Christmas 
holidays being close not sure if this will happen before or after, so watch this space! 
thanks for testing everyone !
