Cartwright took my early kick-off and ran straight for the goalposts, when all I had to say was “so, energy?†In the beginning of Guild Wars 2 development, there were no resources. Or rather, there was just skill recharge. They wanted to start as simple as humanly possible. After some testing, they decided that they did want another resource to balance encounters and give players some sort of encounter-success measure. This was measure was not really found in the original Guild Wars where the encounters were binary; players either won or wiped. Then the designers went crazy with ideas for resources including resources on skills, items as resources, “bars,†and all sorts of things. After a ton of brainstorming and iteration, they landed on the energy bar.
There is a ton of information in this new interview you won't want to miss:
