The summary sounds about right. As for the two topics of discussion:

Turbo duels sound like a cool option. Given the setting and my previous mention in a post that's irrelevant due to my own confusion about matters being discussed, it would open up for a character who tends to any of the gang's duel runners for those who want to turbo duel. Problem is speed spells... I mean, it might be best to can them since introducing custom spells and such might just make things a little janky, but I'm not steadfast in opposition if people are interested. Especially since canning speed spells seems like it would defeat the purpose of a turbo duel being anything other than a regular duel on wheels if memory serves me right.

I like the duel gang concept personally. Again, to me it seems to open up possibilities for character motivation. A duel gang doesn't just have to be full of delinquents. We can have a mechanic who can't get any other kind of work, a former sector security type who got kicked off the force for any number of reasons and wants to try and keep people safe in any way he can, or someone who just loves to ride fast and live hard. The duel gang also ensures that there's plenty of interaction potential, and that someone doesn't feel like they're kind of stuck off in a corner without the chance to interact with people.

In regards to a duel gang, I like the idea of having those NPC and outside threats, but don't want to overload the GM by having everyone duel NPCs the whole time. The stakes of facing outside foes is good and can lead to some interesting drama and possibly recurring rivals. For example, I know a couple of us mentioned wanting to play as underdogs. What if one of those underdogs is forced to play a duel while putting up their duel runner as an ante, only to lose it. It can open up the possibility of someone else stepping in to duel for that duel runner back. Same opponent, same deck, different outcome and stakes.

One final thing I figured might be worth tossing out there as well, and possibly address at a much later time: tag duels could also be interesting to RP and have been Staples of the earlier shows (can't testify to the later ones). Just thought the logistics, possibility, or desire of those could be interesting to discuss as well.
