40 is too long, assuming it's not multiplayer. I still play a game this long if I get the urge to complete every quest / explore entire map. (ie: Fallout 3)
In the end, it doesn't matter to me too much when it comes to money. If a game can impress me, I don't mind if it is short. Sometimes a game is good enough that I'll want to replay it immediately. (ie: Metal Gear Solid 4)
Portal came with the orange box which had so much material vs money that you can't complain about it.
