Full score or just the start? I'm running beamsaber right now, and I feel like I'm building the plane as we are flying, it's a bit harrowing. I don't yet feel like I'm quick enough on my feet to work out everything as we go, and I'm not sure I'm supposed to, really.
I started with an action opening, so like a semi-full score, but it went well. Then we did downtime and next plot hooks. Honestly, I see why you could find it stressful, it relies on improvising a lot, but it's also somehow less stressful for me compared to knowing I have prep work to do before my d&d game. I can actually see myself running two campaigns if one is Blades and other is something more prep-heavy like d&d. I'll if I have the same opinion after few more sessions. I hope I do.
Congratulations on branching out!
I think we need more variety in the TTRPG space. I don't like the idea of D&D being a near-monopoly.
We tried running the system, but it didn't feel like it had much potential for a long term campaign. It was fun using the retcon mechanic to attach a grenade the the lever of a toilet though...
