This deal comes with Guild Wars 2: Heart of Thorns and Max Level boost (also in standard) along with these additional items:
Guild Wars 2 is one of those holy grail of casual MMO experience. You don't need to stress over a monthly payment to grind to the maximum level, nor do you need to shell out thousands of dollars in cash just to get good gears. While the game has been released for quite awhile now, the game has been maturing quite a bit. End-game content, while a bit controversial at times (supposedly you shouldn't have to grind for top-end gears but there's still a bit of that). Regardless of how you feel, I personally think Guild Wars 2 is one of the more interesting MMOs to come out, and can be a fun experience especially if you have a few close friends to play-through with.
