Eric Chahi has done interviews and written in the past about his extremely popular groundbreaking 1990 game 'Another World'. A title which has stood the test of time and is still very entertaining to play today. Another World was updated in HD not too long ago in a Collector's Edition back in 2006. You can check out this new version here.
Just this last GDC in 2011, Eric Chahi was invited to do a Postmortem about Another World. In this video/slideshow you get to see Eric talking about all the fine details of his game. Check out this great resource here from the GDC Vault: www.gdcvault.com.
NOTE: Watch until the end for a really good surprise!
