Nintendo Entertainment Analysis and Development
Kyoto, Japan
Odds are that most people reading this article owe their fascination with video games in some part to Nintendo EAD (Super Mario Bros., Legend of Zelda), so including it on this list is a no-brainer. However, we feel compelled to point out that its not just their work from almost 30 years ago that earned Nintendo EAD a spot; were impressed by the way they consistently manage to push video games as a whole in new directions. Plus, as people who grew up with video games, we think theres something to be said for knowing there is someone out there keeping Nintendos genuinely friendly blue-skies aesthetic alive.
Looking Glass Studios
Cambridge, Massachusetts
Youd think that itd take more than two notable game franchises to get yourself on Game Developers list of the Top 30 Devs of All Time, but Looking Glass Studios earned this just by the strength of Thief and System Shock alone. (We know they did other games, but every time someone suggested including Looking Glass, it was just for those two.) Naturally, we cant bring up Looking Glass without mentioning that Ken Levine started his career there on Thief before eventually going on to found Irrational Games and later creating BioShock.
Mojang
Stockholm, Sweden
Mojang makes Minecraft, Mojang sells Minecraft, Mojang makes millions and millions of dollars. Practically overnight, Mojang became a fairy tale to tell starving indies: Work hard on ideas you believe in, do right by your players, and the money will come. So Mojang is on this list because what theyve done with Minecraft alone is an amazing accomplishment -- and also because we, too, want to believe.
Platinum Games/Clover Studios
Osaka, Japan
Were going to cheat and cover two studios in one entry, since Platinum Gamess core trio of Shinji Mikami, Atsushi Inaba, and Hideki Kamiya previously worked together as Capcom subsidiary Clover Studios. Between the two studios, this dream team is responsible for Viewtiful Joe, Okami, God Hand, Bayonetta, and MadWorld. We like that Platinum Games is unafraid to unleash their creative energies and take risks; we love that they do this and make games that just feel solid, satisfying, and lovingly crafted.
thatgamecompany
Los Angeles, California
Even after Flow and Flower, naysayers and traditionalists had no problem dismissing thatgamecompanys work. After Journeys runaway success in 2012, though, we dont think anyone can ignore thatgamecompany anymore. To us, the fact that thatgamecompanys emotion-directed development approach can thrive and flourish indicates that our industry and our medium are gradually maturing in their capacity for creative expression -- which we think was a long time in coming.
