Just testing Mixer out of curiosity and well it’s even more gamified than Twitch. Numbers everywhere: levels, XP, embers, hearts, sparks, skils. If found a musician to watch, and someone apparently spent sparks to display a GIF in chat that said “today is a good day to be gay”, which is a little surprising but always nice (even more so bc the streamer agreed).
Account creation seems to be handled by Microsoft. Obtaining a streaming key takes 24h (there is an automated validation process).
