Just remember when playing that almost everything comes down to rolling a 4+ on whatever type of dice is appropriate (usually Troop Quality roll). Possibly in opposed rolls. And it’s that or add a dice or two to the roll. Stick with that in mind and it should hopefully not be too confusing.
Though saying that I went to play Tomorrow’s War and instead ended up playing Force on Force and am only just thinking of going back into sci-fi stuff with NSIS…
I wrote the Vietnam version ‘Ambush Valley’
And I’ve been recommending that to people who don’t even play FoF. Very handy reference.
