Communication & Transparency (scrum)
When you’re developing that kind of software for a client, your goal is eliminate all surprises. That’s not the case with a video game, if by “client” you mean players.
Your client also isn’t nearly as many voices to listen to as the entire GW2 player base.
Chances are, they might do some scrum-style work internally, with teams reporting to supervisors. With the developer-player relationship, however, scrum isn’t generally a realistic option.
