I do think it might be worth describing cover in computer game terms - as in this is the bonus you get if you are crouching behind a chest high wall, or if you are shooting around a corner or hiding behind a pillar or whatever, because those are probably situations gamers are going to be familiar with and may want to replicate.
Some supporting text is certainly necessary, and we can perhaps even go a wee bit further than that if the stars align correctly. Will keep it in mind.
And if you can do something like the shoot - hide (health regen) - shoot cycle from Halo that would be awesome.
Given where we are with the alpha right now, I'm confident this is eminently doable with the new system. Seriously, like 1/10 of a step away, if not already there.
And if you can do a G.I. Joe campaign book, consider doing a AAA video game book! Call of Duty and the rest are at least as much of a cultural influence as Saturday morning cartoons used to be.
The Saturday Morning Spycraft series was a little bit of an aberration, and certainly a product of Spycraft 2.0's shotgun approach to "modern." While G.I. Joe will forever remain a core inspiration for the modern rules set - if not Spycraft, which is more espionage than blockbuster action - the rest of that series definitely lives out on the fringe of the core game line, if not well beyond.
Call of Duty and its ilk... Definitely in line for Spycraft Third, though again, not in the core book. It's not the main focus of the game, but will be well supported as we dig into other topics.
