I didn't even know FFG SW code existed, huh.

That said, I feel like the rough thing in the new L5R is that it's still roll and keep but now its roll and keep with meaningful options/decisionmaking, meaning every roll is a two-step process. You can't simply put in a +command and even get a success/failure message. That alone seems like it's going to be incredibly slow to resolve in a MU setting.
