Frankly. I don't get the drama about Lisa joining cam-show. She already did, when this human-waste, brother of hers installed all those cams. Or did I miss something?
I assume they consider "hidden cam" participation as her not realizing that she's in it, while webcam would mean that she's actively participating.
As for me, I don't mind Lisa joining the webcam per se. I just find it boring because it's basically same stuff that had been done with Alice, just that now with Lisa. I value variety in stories highly, so when it's just repeat (webcam again, or the endless porn movie production), it gets boring real quick.
Part of the biggest reason why it's boring is because a lot of the things are designed to be repeatable. If things are repeatable, they are essentially game mechanics only which means there's little to no need of storyline. I prefer a lot more storyline in the game. Sadly we haven't really got any since Kira's arrival because the only storyline that happens now is just the porn movie which has been there for 4 months and potentially at least 6 more months in the future.
