Chaos Emeralds Classifications

This was a little idea which began out of sheer boredom: an attempt to take the concept of Chaos Emeralds, with their variation in number, shapes, and power between games and inexplicable tendancy to disappear at the start of each new installment; and somehow make this plot device canon. And if people can come up with ways to make the Zelda timeline coherent, certainly even I could come up with an explanation for the Emeralds. And so, after a good half hour pondering the enigmatic gemstones, I decided that there could be only one way to tie together every Sonic game featuring Chaos Emeralds without resorting to a multiple-universe theory and placing no restrictions on future additions to the franchise, not even those as retarded as Unleashed and Black Knight.

Premise: There are thousands of Chaos Emeralds in Sonic's world.

No no no, don't click out of the page yet. I promise you that this will not violate all that is good and beautiful about the Sonic canon. For example, I keep the rule of seven intact while simultaneously providing logical explanation for all the little quirks which surround the Emeralds.

All Emeralds belong to sets. Two or more Emeralds can be identified as belonging to the same set if they are acquired through very similar means (I.e. the same-style special stages).
There are four classes of Emeralds in existence. Listed in order of increasing power, they are: Trick Emeralds, Power Emeralds, True Chaos Emeralds, and the Master Emerald.

Trick Emeralds - These are the weakest and most common variety of Chaos Emeralds. They do not allow their owner to transform into a Super form, though they may allow some other kind of transformation or a different power altogether. A set of Emeralds can be defined as a Trick Emerald set if at least one of the following is true:

• There are more or less than seven Emeralds in the complete set.
• At least two Emeralds are the same color (more commonly, all of them are).
• They are not all the same shape and size.
• Owning the complete set does not allow transformation into a Super state (glowing hair, eye color change, invinciblility, etc.)

Games in which Trick Emeralds appear: Sonic 1 MD, Sonic Spinball MD, Sonic 3D Blast, all of the MS/GG games.

Power Emeralds - These are much stronger than Trick Emeralds, and much rarer. They always come in sets of seven, they are of uniform shape and size within the set, each Emerald is of a unique color within its set, and a complete set of Power Emeralds allows transformation into a Super state.
Games in which Power Emeralds appear: Sonic 2 MD, Shadow the Hedgehog.

True Chaos Emeralds - These are the real deal. Only 7 of these exist in the entire world. The True Chaos Emerald set has all of the properties of a Power Emerald Set, but only True Chaos Emeralds can be upgraded into Super Emeralds. When all seven True Chaos Emeralds have been successfully upgraded, the owner can transform into a Hyper State more powerful than the usual Super state.
The only game in which True Chaos Emeralds appear is Sonic 3 & Knuckles.

Master Emerald - You know what this is.

So this is the basic idea, with no frills attached. But since this concept restricts itself to the current Sonic canon, it fails to explain why the Master Emerald is chased after only as often as the rest of the Chaos Emeralds. This is easily solvable with only the following alterations to the above:

7 sets of True Chaos Emeralds (for a total of 49).
7 Master Emeralds, each associated with one of the True Chaos Emerald sets.
1 Master Master Emerald.

But by this point, I'm worried that I'm venturing too far into foreign territory, so I think it may be better to just leave it at 1 True Chaos Emerald set and 1 Master Emerald.

Opinions? Suggestions? Ridicule?
