I'm sort of in agreement with Derran's argument that one an interdiction field is established, we could use only sublight, which would give some room to talk in starship battles. With super-FTL weapons, you don't have so much room for the crew to react or recieve orders from their commanding officer - the Miharu's first real starship battle had the CO giving order to the crew that they tried to interpret on the fly because they needed to react quickly due to the need of making FTL jumps and the presence of superFTL torpedoes. Remove that, and you have a little more room to breathe and roleplay things out a little more intelligently.
From that point, it's really the GM's position to decide how fast paced his battle is, but he'd have a feasible excuse to squeeze in more time.
So, I'd make an assumption that Interdiction tech would allow to affect an area locally, or on a more massive scale. The state would be either that that the conditions are normal, that you cannot use your fold drive or that you cannot use your superluminal drive. A 0 or 1 value, really. And then, if we keep to relatively small values (see my post above yours, Cannonball), then we might limit the headaches to a minimum.

This thread is all about re-evaluation of FTL/Interdiction technology Zack. We are also going for overhauls pretty much everywhere else since Andrew decided that set precedent was no longer an impediment to fixing things. I'm just getting started, you know? And seeing my goal is to make things more coherent and give environment greater value (some things in space should matter), this only makes the importance of it greater because players being able to relate more to things is in my eyes important.
Therefore, Wes is not limiting my options with his thinking that 'a 1 to 10 DR-like scale would be okay'. My thinking goes much more in line with Derran's this time around.
