Apparently few people on this site know your actually a PC gamer ssj hehe. I remembered at least

i'm thinking of picking this up, but i'm VERY strapped for cash right now. i was wondering, do each one of the games in orange box have a single player mode?

 if you want just HL2 the first game I have 1 gift card on steam for 1 free download... oh and one for HL2: Lost Coast too.

Neat they added a timer now, so you can see when it is supposed to launch!

Now we're on VALVE TIME! 

Well we are under a minute to go, and so before I don't look at the boards again for a few days, I just wanted to say ENJOY =)~

Here we GOOOOO!!!

Portal rocks. I've played through a bunch of puzzles...so great. The announcer in the background is so funny...so dry...messing around with portals is great too.

All I can say about portals is WOW! Its actually better than I expected =P

Ok I am going to go into spoiler mode for those who don't want to know ANYTHING. But I promise I am just going to talk about the amount of content and nothing specific to what you are actually doing. So if you are curious how much there is to do this will answer your question without ruining the puzzles.

**BEGIN QUASI-SPOILER**First of all there are a total of 19 puzzles as part of the Aperture Science Center program. Then once you have completed those there are some "extracurricular activities" you will undergo which can take quite a while (45-75 min or so just for that extra bit after the main 19 puzzles). Then you will have the opportunity to play puzzles 13-18 iirc on "Advanced Mode" which basically removes a bunch of the easy ways of doing things and makes life difficult all around. In general these are pretty hard but if you are dedicated you can finish them. Then they have medals to earn ala Wii Sports where you are trying to compete in Puzzles 13-18 again but you are competing in 1 of 3 categories. You are either trying for lowest time, least steps, or least portals used. Each category for each level has a medal to win (bronze, silver, gold). When all is said and done it will take a LONG time to get all gold in these levels and it would probably take a decent effort to get all silver.

But once you are done with that stuff you can get cracking on the level editor leaving you pretty much an infinite amount of content so long as the community remains strong.

**END QUASI-SPOILER**

In summary there is plenty of content for Portal.

BTW, valve has confirmed Map/Level Editors for TF2 & Portal for those who don't know. And if you're like me that practically sells the game by itself!
