If themed streams will truly be regular on a bi-weekly basis from now on, why not make some of them connected to each other and form a kind of longer story?
I presume the two AIs will take turns each as well, so either could follow their own story-beat, or the loose tales may be conjoined.
This type of content could make extensive use of memory capabilities as well as the integration of props that call-back to the previous themed stream.
This suggestion by no-means targets all themed streams. But every now and then, a smaller story could be developed. This might be planned already with a heist stream and then a prison stream. Nonetheless, I want to put this idea visibly forward.
