Visits to Jagex HQ are the pinnacle of many a Runescape players desires.
Mark Gerhard likes to take the boys in rides in his tank. When asked why he had a tank, he jokingly replied it was because of his penis size. And we all laughed. The first ones to stop laughing were banned from Runescape.
Many players have enjoyed the delights of Jagex's pleasure palace. As long as they had something Jagex wanted.
And this is good business, give obedient and willing players some rewards in order to encourage similar behaviors in other players. But make sure those rewarded players have public exposure, so that the good things that Jagex does can be trumpeted to the heavens.
For free and for ever.
