I guess we just have to agree to disagree. Using the 1d20 +/- mods versus DC mechanic from the 3x SRD for most task resolution and combat really places it closer to the SRD end of the spectrum for me. It pays crazy homage to B/X for certain but, mechanically, it cleaves very closely to the 3x SRD (the notable exceptions being multiple XP advancement tracks and theif skills).
Most? What else besides the attack roll? And inverting the AC is just a stylistic choice, the progression in combat prowess is much closer to B/X. I'm currently running B3 with BFRPG and the only change I had to do was switch the AC for the characters since I much prefer descending AC. BFRPG is rquite close to B/X and has basically nothing to do with 3x. This is also the stated intent of the author as expresses in many posts.
