Valve's Chet Faliszek and Eric Wolpaw conducted a Portal 2 postmortem at GDC last night. The writers talked candidly about alternate endings and the difficulties of following up on their critically acclaimed first game. Chet also mentioned that, at some point in development, the team experimented with competitive Portal 2 multiplayer modes.
Relax. All done now. Potatoes collected, game digested, portals spent.
Time for more Portal 2! After finishing both of Portal 2's campaigns we sat down with writer Erik Wolpaw to discuss what was – and wasn't – featured in the return to Aperture, the game's ending, and a lady with an especially sexy voice. Needless to say, if you haven't played Portal 2 to the end, this is spoiler PACKED. So don't read any further until you've completed the thing.
