So, I'm looking for a rarity guide for the NES library that's accurate and up to date. Theres 2 guides that pop up on Google, that seem pretty good, but they don't exactly match up with everything. So does anyone know where I can find a guide that's pretty accurate?

One guide rates the games from "E" to "A+", games like Excitebike and SMB being an "E" and Stadium Events being an "A+". The other rates the games by 0% to 100%, with much of the common games being at about 15%, while Bubble Bath Babes being around 97%. Idk how up to date these are, but Tengen Tetris and Die Hard were rare when these were made, they're still rare, so how much does it really change?

Idk if it really matters that much, but I'm just curious if there's a real up to date list somewhere.
