Well obviously Beat Saber is a big must, but that is easily handled with the button issue,
Half Life Alyx, Boneworks, Skyrim
And some of the horror games come to mind,
I would honestly love to try them all, especially the ones with VR support that arent just VR games, such as Skyrim and Phasmophobia
Beat Saber has a one handed mode!! I think Alyx has one too.
The ones with VR mode that aren't VR mode will be the hardest to do if you want to use the Touch controllers. You could use the xbox controller of course but that will ruin the immersion.
