I thought peertube attempts to be a complete replacement

Dude no one can figure out ftp. Before there was yt there were embedded QuickTime videos and video podcasts

I think you can use web browsers with it

Element isn’t replacing shit. I hate Matrix

I’m a fan of Freedroid Classic, a FOSS remake of a commodore 64 game called “Paradroid”. You’re a robot on a deserted space ship full of other malfunctioning robots, and you have to hack / shoot all of them. You start out as the worst robot, but if you encounter a better one, you can hack it to take over its body – if it doesn’t kill you first.

Takes a few runs to get the hang of it, but it’s a lot of fun.
