Portal only open four hours
Kim Swift, Valve's level designer stated that Portalclocks in at around four hours to complete. As a standalone retail game, that would be quite disturbing, but given that it's accompanied by four other titles in the Half Life 2: Orange, we're a little more forgiving. Still, the game promises to be a bit of a mind-frack, though Swift promises that the difficulty curve isn't going to be overwhelming as the game teaches you to "think in portals". So, are you going to put into the better part of an afternoon into this when you pick up Orange later this year, or are you going to stick with Half Life 2 and its episodes with a side of Team Fortress 2?
