Warhammer Online: Age of Reckoning Interview

GameIndustry.biz will have an interview with Josh Drescher about WAR up next week, but releases one tidbit now: WAR is set for five years of content.
"All the under-the-hood numbers all actually scale through the next five years," he said.

"What you don't want is when you launch the game you've got 40 levels - and it takes however long it takes to get to level 40. You then launch an expansion and it now takes two weeks to get to level 40 because now we need everyone to spend six months to get from level 40 to 50," Drescher added.

"So you need to spec the game out in such a way that you actually have those progressions in mind for later - so you don't wind up trampling all over the earlier experiences every time you expand the game."
