Iīm currently writing a lengthy review of the book, although based on the german version which dropped a week earlier for whatever reason. A few observations:
First: thereīs definitely some improvement to the current state to the game, PLUS the overall quality and clarity of the rules has also improved compared to the CRB. Sure, some of the "fixes" (like the MA quality that adds a Strength-Based Damage Bonus to melee Weapons) come a little too late for me, since I already houseruled stuff like this. But I can still rework the new additons to integrate them with my current set of houserules,
and these might be just enough to help out tables without houserules.
However : Thereīs one major flaw which, despite various complaints AND various statements that there were big improvments coming, isnīt adressed at all, and itīs dragging everything down. At least in the german version, I found ZERO additional rules for the AR/DR comparison. And that is not just a problem because "ArMoR dOEs NoTHin

" (there are actually armor options that do help with damage soak now, although these are a bit gimmicky) - itīs a problem because the vast majority of the new perks and tactics in Firing Line
only affect AR/DR values. So you meticulously pick out one of the 6(!) different Gunstock options plus the right Recoil Compensation for one of the new Guns (which also mostly just introduce different AR arrays) to get the perfect beast for the job
and then you also ace one of the new Combat maneuvers with your teammates (which
also mostly just affect AR/DR)
only to push some numbers around that donīt do shit anyways - because you already beat the difference of 4, because you have already earned your 2 Hardy-approved Edge for the round, or forgot your morning cigarette or because (and I will
never stop bringing this up) because you do the wildly unconventional tactic of
Sniping out of Cover with a Scope.
In short: If you donīt already have some kind of houserule to smoothen out the Edge Limitations and/or make the AR/DR comparison have a bigger impact, 90% of new options are worth shit in 90% percent of cases.
Or am I mistaken here? Iīve seen various semi-official statements that AR/DR will matter more in the future. Is there something in the english version thatīs missing in the german translation? Something in the Errata?
