If we want a consistent rule, my suggestion would be to capitalise any terms that the game is redefining away from their standard English meaning. So, e.g., Shiny would be capitalised because it doesn't have the meaning of "anything that shines", but rather is a specific sort of game object.
That's pretty much how it was back in the nineties (e.g. Rule was pretty much always capitalized). As G. mentioned, there seems to have been an intentional drive to decapitalize terms in the mid 2000s.
