Portal is one of breakthrough titles that came in 2007, combined in The Orange Box with other epic games like Half Life 2. Though people would look forward to a "Portal 2", Valve says they're going to take their time to bring out a quality game just like the first one instead of rushing through saying "Okay, that was revolutionary, so its successor has to be equally as revolutionary".

Portal was a breakthrough title that prompted a lot of people to pick up the deal of the century disguising as The Orange Box. There’s something oddly satisfying about hurling yourself through one end of a portal and leaping out the other while avoiding wise cracking sentry guns. Be that as it may, while we know Portal 2 is coming, Valve is planning to take their time with the follow-up.

“I think that when you hit something like that, you have two choices: you can quickly replicate it and stick it out there - do the opportunistic thing and cash in on it - or you can do the crazy thing like we did after Half-Life was so successful and go off and try and say, ‘Okay, that was revolutionary, so its successor has to be equally as revolutionary” said Valve’s Doug Lombardi.
