It might be instructive to compare this less to what exists on Ares now and more to Arx's "flashback" system, which you can play via web as well as on the game and are designed to be asynchronous.
I think my biggest struggle with engaging in those/remembering I'm in them is, if I'm not online to get the @inform when there's a new pose in them, I frequently totally miss that there's been activity in them. Like, I'm someone who does pretty well with the Ares scene system but mostly can't manage flashbacks so idk exactly what the difference is. It might just be a matter of how much they're deemphasized on the Arx website (you have to click through your character page to get to your flashbacks and then into the flashback itself). Also might be a cultural thing, idk.
