			HM is more complicated than 3E, not less.
		
		
	 
To quote "The Dude":  "That's like, your opinion, man."
In general, I find it easier to remember if I need to roll high or low in a situation that it is to remember what feats, skills, synergies, conditions, etc... go into the modifier.
d20 has a simple unified mechanic: d20 + mods.  But the devil is in the details of the mod.  Sometimes determining what mods apply require stopping the game and thumbing through a 300+ page book.  d20 (at least D&D 3.x) is *not* any simpler than previous editions of the game (and by extention, HM) simply because it uses a single mechanic for just about everything.
Now, if you want to talk about the time/effort needed to track honor and alignment in Hackmaster, I can turn the wheel while you grind the axe.  However, you can drop that stuff from HM and wing it, while still retaining the HM flavor.
Johnie Freedom: I'm in the middle of re-editing my house rules for my Basic/Expert D&D game, which includes options for eliminating the "race as class"  stuff, and replacing them with an AD&D like system.   Let me know if you want to have a look at them, and I'll post a link when the edits are completed.
