Question / Advice: My small group of friends who've met-up once a week for 20+ years need something web-based to stay sane during lockdown. What do you play remotely with friends in a browser?

Me and three friends have gotten together every week for over 20 years now to play games. In the past it's been whatever the current consoles are, but now we're all stuck inside for the foreseeable future, and want to stay in touch.

I'd love to find something web-based (two of them on PS4 these days, another Xbox, me on PC) that we can get together to have a laugh on a few hours a week. I thought of setting up something on something like Roll20, but getting them to buy into proper RPG will be hard. So I'm open to suggestions really. Roll20-lite would be cool, but I'm not sure what's out there.

What do other members here play to stay in contact remotely, that requires nothing more than web browser?
