Personally, I'd find it a bit more complicated to use, for example,
Tome of Battle: Book of Nine Swords with
Shadowrun or
Legend of the Five Rings (d10) than using it with
Castles & Crusades. YMMV, obviously.
This is why I made the distinction about the "d20+adds versus target number" mechanic earlier. While it may be more difficult to use (f'rinstance) the Book of Nine Swords with Shadowrun than C&C (which I 100% agree with, BTW) it will be
just as easy to use it with the default Target Games engine as it is with C&C (both are level/class systems with the same basic core mechanic).
Similarly, using the product in question with the BFRPG, Advanced Quick 20, Legends, Core Elements, etc is just as simple as using it with C&C (possibly moreso in the instances of Quick20 and Core Elements). Point being, C&C doesn't exactly have a corner on the "easy conversion" market. It's a definite plus for the system sure, but as I mention earlier, the easy converison is essentially house-ruling.
That is, there aren't any
rules in C&C for feats, challenge ratings, etc -- if you want to use these things, you can, but doing so requires some house rules (i.e., it's up to you to determine how they work in C&C). Same thing with any of the other systems mentioned above. So it's less about true conversion than it is about easy modification.
