First off, best of luck on your Lets play show. May it prosper in the best of ways.

Personal opinion, there is no " how it should be done " in any form. While I can agree that others could stand to be more kind to newbies wanting to see the story, On the other side of the argument, your running on other peoples time ( same can be said vice versa ).

There is no right or wrong, how it should or shouldn't. Only thing that should be done is being kind and considerate to others. I do my part to let folks watch the CS, regardless if its a main story of not ( there are a lot of neat non-main story CS ).

I recommend doing a pre-made ( unsynced optional ) next time for a show rather then counting on randoms.
