Fire Control & Speed Factors

CRM as always, very detailed thinking here.

I really like a lot of the concepts here - as it turns out - this is one area of my own house rules I have not firmed up - so all the comments and content here are very fascinating to take into account.

It does seem easy to blend in speed and scale - which makes sense - but the question is also about how different the scale is as well.

Now, I am trying to come up with something more simplified - but that is just personal take in trying to overall have my rules at my group's desired intersection of detail and ease of use - everyone has their own threshold.

I am working one something that might be a bit more subjective - but requires less rules and/or charts.

Not sure if useful....but

Pak's Field of View Target Movement Modifier
From the point of view of the shooter - how far does the target move across their field of view.
After Range and Scale have been factored, then modify by target's intended movement for the round.
For each full 45 deg of apparent movement from the perspective of the shooter - increase the Difficulty Level to hit by 1 level.

Example;
Turret on a ship targeting an fighter.
Beginning of round fighter declares speed.
Ship targets fighter, based on range and scale - requires Moderate to hit.
Gm looks at where ship beginning of move, and end of move.
Determines more than 45deg but less than 90.
Difficulty increased 1 level from Moderate to Difficult.

Example:
Character shoots at Awing flying over head.
Beginning of round awing declares speed - it is very fast.
Character waits until closest point - gm determines range, and adds scale - base difficulty without speed is Very Easy level difficulty.
Gm looks at distance - it is starting on one side of character and easily crossing completely other side 180degrees.
GM counts this as full four 45 arcs - and increases difficulty 4 levels, from Very Easy to Very Difficult.

Why arcs and why 45?
Because it automatically factors in the concepts of range and direction of movement - you can just look from the perspective of the shooter - and see "how much did that move" - this takes all the potentially complicated vectors and everything - and makes them simple. (not, not perfect - but simple).

heck, this even works with chases - as vehicle moving fast is difficult to hit from the side - but from the following vehicle - the relative movement is less (why dogfighting works). Again, not perfect- but simple.

I go with 45, as it is pretty easy for most folks (and the gm) to visualize, and with each being so large - there is no need to break out a protractor or anything (it is pretty obvious if over 45 or 90 etc.).
(we already have a measuring thing with 45/90 etc. on it for are starship battles, so can just take that out of the game box if necessary).

So...
Is this perfect? No.
Might this be what will work for my group's game: maybe.
Will this work for others: some yes, some no.

I know that the system presented in CRM's posts are interconnected - and within that structure speed codes and everything else already exist - so something complex fits in that structure - but then again - maybe what my group is playtesting (we have used it for about 3 months or so) can be useful in some context or something to someone.

May the wild die be with you....

The baseline Velocity Modifier is calculated on the base Move of the Character / Vehicle. Because the Move Levels are predicated on doubling the lower value (x1/2, x1, x2, x4), it lines up perfectly with the x2=+1D formula, and thus every Move Level is a 1D step up or down from the base. Thus, a character moving at his normal Move adds his Velocity Modifier to the shooter’s Difficulty. If he’s moving at Cautious, it’s Velocity Modifier -1D (because it’s half his normal move); if Full, it’s VM +1D (double normal Move); if All-Out, it’s VM +2D (quadruple normal Move). The idea for everything in this rule is, the faster it’s moving, the harder it is to hit.
