You know, one of the fitness principles that helped me for years and years was that idea of 'I'll just go and stand on the treadmill' which is exactly what you are doing, and that's awesome. It means that you are not disengaged from your story!
I am excited to start writing today, because I am into the last 2 chapters of Act I, when the fantastic/sci-fi element gets introduced and the premise gets lore-dump-- ahem, explained to my sweet Werewolf-to-be. And his "what you want" for Act 2 becomes clear.
On the downside, I will have to describe the Team, and I always dislike writing those intro scenes when a lot of people have to come on board. I am cheating a little, introducing three of the characters a little earlier in 'quick glance way'. But I still have three more to round out the research team. Ouch.
But, I will keep Assassin Creed (modern day portions) close to my heart and go for it.
