Link gives me a 404.

If a friend of yours would invite you to play some Card Game over a tool that is focused in the table, not on the rules, would this be ok?

I am not a fan of playing in person games on a computer. Especially if we are in the same location.

There are so many simple open-source tools for that, that I would rather think about joining an existing project instead of creating another one

There's a range of virtual tabletop software or SaaS out there. The two things that have kept my group from adopting any of them are: 1. Zoom is free and has been "good enough" for us so far, and 2. tech learning curve to create and load maps and encounter data into a virtual tt solution.

I'm the most tech-savvy of my group but I am not the gamemaster so I don't have leverage to push for adoption of a VTT. I agree about simplicity - we'd be fine with basically a video conference client (with screenshare whiteboard overlay ofc) and just a virtual dice-roller added.

Table top simulator comes to mind. https://www.tabletopsimulator.com/

I used https://fari.app/ and loved it. They discontinued because of the dependencies.
