40. Anita Sarkeesian, critic, Feminist FREQUENCY
The common depiction of women and the lack of female representation in the industry is a serious problem for games' ongoing development as a serious cultural form. Sarkeesian is doing much to keep these concerns in the public eye.
39. Satoru Iwata, president, Nintendo
Every developer, publisher and platform holder can still learn from Nintendo's eye for a popular idea and care and talent for making it perfectly, and from Iwata's will to speak directly and enthusiastically with players.
38. Antti Ilvessuo, creative director, RedLynx
Trials is one of XBLA's evergreen series, its exacting challenge the result of some seriously tight design that also has a wicked sense of fun (by which we mean sadism). It's a mirror, then, of its creative director, Antti Ilvessuo.

As one of the team that squeezed the infinite worlds of Minecraft onto Xbox, Paddy Burns performed a technical feat with the kind of reward that comes with four-player split-screen creation and managing XBLA's biggest game.

With a background in translation, Woolsey worked on bringing Final Fantasy VI and Chrono Trigger to the West, and now brings games to all Microsoft platforms, from Xbox to Windows Phone. Microsoft's vision of games working across them is down to him.
35. Marc Doyle, co-founder, Metacritic
In charge of Metacritic's game listings, Doyle indirectly - or perhaps not so indirectly due to the secret weightings he gives publications - affects both the pride and fortunes of devs. His Metascores, after all, help define their reputations.
34. Frank Gibeau, president, EA Labels
The biggest game publisher in the world is facing many challenges, and Frank Gibeau is tasked with leading its four internal labels, which represent all of EA's biggest franchises, to bring the supertanker around.
33. David Helgason, CEO, Unity Technologies
The free-to-use Unity engine is the technology behind an increasing number of games on all platforms and of all styles. It's been used to make everything from retro 2D curios to 3D blockbusters.
32. Perry Chen, CEO, Kickstarter
Perry Chen's company, Kickstarter, has given developers an amazing new way of amassing the money they need to make games without having to bow to publishers' tastes. That means a greater variety of games being produced - a great thing for all.
31. Vince Zampella, co-founder, Respawn Entertainment
After confirming in March that his partner, Jason West, has left Respawn, Zampella said he was finally set on revealing Titanfall at E3 this year. At last we can see if the Call of Duty originator can repeat Modern Warfare 2's success.
