This was posted to RGP 11 years ago and is the definitive answer. Thanks to Chris.
"A highly qualified panel of five judges (Max, Mr Badazz, Chris,
Christopher, and Chris(in NH)) spend countless minutes putting this
together during lunch, based on trend, availability, price, demand,
and overall RGP opinion.
Here it is....... use it as an official doc to base your sales prices
and trades.... this is for DMD games only for now
A List - an elite special group with a high demand and uber-high
prices. They are the titles every man wants and every woman wants
their man to have: MM, AFM, CV, ToM, MB, TotAN, SM (red or black),
TSPP, SS, LOTR, BBB, TZ, Tron LE, TAF, IJ, CC, and SC.
B List - great games that command lower prices but still in demand.
The B list also contains any flavor of the month games that come up
from the C list (like RBION) and newer Sterns that have been recently
released and have not shown a longterm trend yet (like ACDC): WH2O,
POTC, STTNG, FGuy, IM, CFTBL, BDK, RBION, ACDC, RFM, TF LE, Shadow,
NGG, GnR, CP, Tommy, PM, Shrek, Tron Pro
C List - average games that are fun to play but may not stay in an
average collection for a long long time other than a persons personal
love of it. These are games that are easy to find for sale and are a
much more affordable price. C List also is the bucket for anything
else that is not in A, B, or the dreaded F : JD, DM, HS2, T2, T3,
Monopoly, RCT, Avatar, TRS, SW (DE), SWEp1, TFTC, IJ4, RS, FT, DrW,
I500, Congo, W?D, SST, JM, BR, NF, Vette, A13, NBA:FB,GoldenEye, Mav,
SMB, Freddy, WWF, MCastle, Sopranos, CBW, BayW, JB, DH, Godzilla, HD
(any edition), BF, Twist, BShot, Viper, TMNT, MarioA, SP, BBH, MSF,
WPT, 24, CSI, NASCAR, Stargate, WCS94, JY, JP, BSD
F List - true stinkers. These titles have small followings but are
considered awful by most. Prices run low on these games and tend to
show up on the monthly rate the worst game threads on RGP: Popeye,
LW3, X-Files, StrikerX, HRC, SShootout, SWT, LW:JP, LAH, Flint, PZ,
R&B, R911, NBA(Stern), SnS, WipeO, TOff, Hook, WoF, Hurricane, Playboy
(Stern), SF2, SJam, Shaq, SMB:MW, GI, AGBGWT, Gladiators, PPoker,
WChallengeS, FT:BH, H2OWorld, Airborne, BarbW, AP, NFL, ID4
FYI, my two favorite games... Jackbot and Flintstones are C anf F
