Well from experience i can suggest that relative to ones personal measure, there's a tipping point where a gracious gesture turns into expectations if the spending keeps happening

Maybe frontier should issue a safe use warning on the arx buy button.. "if you keep going we're not like the others here"
I don't like the movie comparison anymore because.. who goes to the cinema anymore for regular entertainment? Or as an alternative to games? That comparison started in the early 2000's when the cinema still played a part in societies. Its outdated and luddite and i think games should be measured relative to other games. Especially because the score dramatically changes when you line up apples and apples.
