Is Portal 1 too short?

[Man Meat]

Or is it more quality over quantity?

[Repudiator]

Quality. It's the same with this game - the single player can be done in about 6 hours if you are good enough. But it's so well-designed that you can be left on a single puzzle for hours trying to figure it out.

I think it has a perfect length. It's better that it is compact than for exampel pointless travels between stations that does not give you anything.

Every Valve's game is the best! Not too short, not too long, but perfect

Quality over quantity.

[JOSH]

Quality over quantity.

I actually felt Portal 2 was too long by comparison. The 60s stuff was neat for awhile but then it just got old, and by the time I got 'back to the future' (so to speak), I was bored and wanted it to be over.

who mentioned portal 2?.. as for portal 1.... (the original question)

YES its WAY too short..

some of the tests are kinda confusing, but I'm no genius, and completed it in less than 2 hours on the first playthrough. Problem is, it introduces the game mechanics, once.. and then it just moves on. Its kinda like the whole game is a tutorial... Dont get me wrong.. the game is amazing.. but there are 20 test chambers (not including dlc and challenges).. the toughest chamber took me a whole of 10 minutes. -.-
personally i was expecting a lot more tests, not to mention much more difficult tests...

Portal 1 was an expirement.

still... it coulda been longer. experiment in what btw? apart from the fact that they could move, the whole "portal/physics bending/ camera texture" thing was basically the same as it was in PREY(different game engine ofc).... or am i completely wrong..... im not wholey sure on how it was done.... but the effect is basically identical.

:edit:... the commentary cleared it up for me..... the gameplay sounds like it would be impossibly difficult to get right. and its more of a buildup to portal2
