Waiting on the Frankenstorm - It Moves Slower Than an AD&D Class E Flyer

This storm is taking forever to get to NYC. I'm sure it will be the equivalent a Old Red Dragon, but it's got the maneuverability of a block of wood:


Class A: Creature can turn 180° per round, and requires 1 segment to reach full airspeed. Creature requires 1 segment to come to a full stop in the air, and can hover in place. Class A creatures have total and almost instantaneous control of their movements in the air. Examples: diinn, air elementals, aerial servants, couatl.

Class B: Creature can turn 120° per round, and requires 6 segments to reach full airspeed. Creature requires 5 segments to come to a full stop in the air, and can hover in place. Examples: fly spell, sprites, sylphs, giant wasps, ki-rin. 

Class C: Creature can turn 90° per round, and requires 1 round to reach full airspeed. Examples: carpet or wings of flying, gargoyles, harpies, pegasi, lammasu, shedu. 

Class D: Creature can turn 60° per round, and requires 2 rounds to reach full airspeed. Examples: pteranodons, sphinxes, mounted pegasi. 

Class E: Creature can turn 30° per round, and requires 4 rounds to reach full airspeed. Examples: dragons, rocs, wyverns. [DMG, p. 50-51]

Because This One Goes to Eleven!

Has anyone put together a list of the D&D retroclones / derivatives and the like in order of relative rules complexity? I'm avoiding the "crunch" label so as not to offend sensitive readers.

I'm talking everything from Swords & Wizardry (all 3 flavors) to Hackmaster (2 flavors) and everything in between and beyond. Besides being a useful list of clones in general, a nice chart would help the prospective GM find a game that is right for his gaming style while still being familiar to those that grew up on Gygax D&D up though Pathfinder.

I realize that much of this would be subjective, and the complexity label might work better as a general banding system.

If it hasn't been done yet, would there be an interest in seeing one get completed?
