I do it for my own personal amusement but it does mean something.
Interest (1-100)= I won't go out my way to look up info but if I see someone posting something, the higher the stats, the less likely I am to ignore the info.
Intrigue (1-10)= How likely I am to go out of my way to find my own info on the game.
Hype (1-10)= How likely I am to tell others about the game.
Fanboy (1-5)= How likely a day one purchase the game will be.
Kudos= Refers to special innovations that a developer is trying to accomplish with their project that I find fascinating. e.g The script for Heavy Rain being 24k pages long.
It's possible for a game to make me lose interest but those "stats" are less defined.
