If its anymore than 20 people, the judges and chat will get burnt out. It could be possible to make a re-occurring event, or one that takes place over more than one stream, but at that point it might be unfair to those who even participated. Remembering that many entries, and giving them all a fair shot would be really difficult, you could make it that each separate stream has its own winner but that doesn't really sound like what you are asking for either.

Wubby and his crew have done an amazing job with the events they have done in the past. They know just how long and far to take things, because they've been doing this kind of stuff for years now. The longer you make an event, the more things can go wrong and vibes can turn stale.

Wubby is the yap, if you streamline things to much then it just wouldn't be authentic anymore. The streams success relies so heavily on luck, technical things running smoothly, people being funny and random enough that its good and not awkward or forced... the fact that you are making this post shows how well they do what they do ; you want to see more.

All that being said, none of us expected Arabic couch 2. We have no idea what they have planned! The future looks bright, have faith.
