Eric is clearly a genius, I assume he hit a sophomore slump. He's only made a couple games since, many years later.
Even with just one major game to his name, its legacy lives on. Another World set the template for the "cinematic videogame" and even today you can see the influence of its cutscenes and minimalist gameplay on games like Ico/Shadow of the Colossus and a plethora of modern indie games. It accomplishes with wordless dialog what Hideo Kojima tries to do with 20 hours of overwrought monologues.
I couldn't agree more. It's one of my all-time favourite games. I replay it every few years.
