having similar issues.. I run a number of training coursers - and recently ran a user story course over zoom, which was ok as we could break into zoom rooms and 'write' stuff together.

I was going to take a look at the XP Game again. maybe get attendees to make paper hats or find cards in a card deck, will need a lot of moderation and an assumption that everyone has access to materials.
