Good rule of thumb: if it's described in a fan wiki, or if there's footage of it anywhere on youtube, it doesn't count. The larger the game is contrasted with how obscure your entry is will make for a better post, but games past a certain popularity basically have their insides torn asunder provided they're at least a year old.
This will naturally lean towards older titles, although I will start with something from a game just last year.
The infamous Metroid Prime Blast Ball, despite its fan backlash, had a fairly large playerbase given that it was entirely free with online play. The game has random powerups, which normally consist of a Shield, Speed Burst, or Eject.
A 4th powerup, missile (which gives you unlimited missiles for a set duration), is so obscenely rare that I've only encountered it twice in over 30 hours, and I've only ever heard of one other person getting it. To this day this screenshot I took (along with its miiverse post) is the only consolation that I have that I wasn't crazy. It's so rare that it may have even been just a glitch of a leftover powerup idea, and NLG may have even patched it out by this point.
