I've been toying with converting the wonderful narrative starship combat from CODA into d20. Although I like CODA a lot, I own a tremendous amount of d20 material and much of that material can, with little work, dovetail with ADB's Prime Directive d20 Modern. Plus, CODA and d20 are so similar to me (*ducking*), that I'd just be running CODA as a d20 game inadvertently in a short period of time.
With that said, does anyone have any advice on how to start? I know that the math would have me multiply a CODA "stat" by 1.6 (1 on 2d6 being 1.6 on a 1d20), but a cursory look at the narrative starship combat rules seems to indicate that I just need to compare CODA TNs to d20 DCs; I'm less confident about that.
If I use the math, the d20 DCs may be a bit high: a TN 10 (Routine) becomes a DC 16 (Tough). However, if I just convert TNs directly to DCs (a TN 10 is a DC 10), it doesn't seem to go far enough since TNs seem to peak at 25 (Virtually Impossible) and DCs peak at 40* (Nearly Impossible).
*Which, interestingly, is 25 x 1.6!
I guess I may need a bit of guidance on skill DCs and levels - like, what is considered an average DC for a 1st level character, 3rd level, 15th level, etc. That may determine how I scale it. If a maneuver takes a DC 30+ to pull off, obviously a 1st level character won't be pulling it off! Still, if it takes a 15th level character to do it, well... we may never see that maneuver performed.
Maybe too much info, but:
To add to the problem, the Deflector Shield Protection of a starship is in effect the TN to hit the ship! I really don't want to mess with the published stats, although one stab at this problem had me adding "2" (1.6 rounded up) to the published DSP (although I can't recall the logic right now).
Anyway, any help would be greatly appreciated! Narrative starship combat is the way to go for an RPG and I love what Decipher did.
