But why? Because thinking up creative ways to entertain your toy guinea pig is hard.
"Here, toy, a tread mill. Now let me just enjoy watching you."
So, in an ironic way, it seems that a lot of folk at ArenaNet do not actually perceive their presence at the office as work, but as play. So they structure their "work" as a play.
Which, still ironic but not actually funny, is exactly how they advertise their job positions:
What we offer:
Fantastic game room filled with ping pong tables, foosball, XBOX’s, PS3’s, Wii and more
Amazing office complex that is filled with GuildWars2 artwork
(Cue "The Walking Dead" episode: "We are the walking dead.")
They did not build a toy for us. We are their toys. Which also explains why they can throw away stuff so fast: they never really worked to achieve it. It's just a game for them, i.e. the development process is a game.
However, a wise man once said:
Business is war in a sense that the casualties are real.
