Deceased son’s steam account ?

My son tragically passed away in October and I know he had a massive collection of games from steam. At the moment I’m not looking to do anything but when I feel able is there some way I can maybe give back to the community ? Gift his games etc. So that someone can get some use out of them ? I don’t want to close down his account as that would be like erasing his existence. Just looking for some positivity in all this.
