A gamer term in the same vein as "a winner is you", "full of win" is a positive descriptor of a person or thing. Things or people that are "full of win" are likely to be victorious in contests or comparisons of popularity, humor, quality, game score, etc.
The new Konami game is so full of win! It's sure to be a best-seller.
