origin
I can't find this option in the interface; but am wondering if maybe behind the scenes the data is available somewhere, or in some hidden corner of the UI.
I was curious how much time I've spent in the Mass Effect universe. So I fired up Steam and checked the hours played in 1 and 2. Then I jumped to Origin to see how long I spent in 3 – but it doesn't seem to show this information.
Is it hidden there somewhere?
Origin does not support screenshots. You will have to use FRAPS or Steam to make them or the game's functionality if there is any.
Assuming windows 7, you should already have a shortcut available in your windows Games folder. For me, this is located at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Games.
Alternatively, if you hit the start button (or windows key) and type "games explorer" and open the folder it displays, it will list all your registered games. 
.
From either of these folders, you should be able to right-click-drag the game's icon onto the desktop, and selecting either copy here (games folder) or create shortcuts here (games explorer)

It appears that Electronic Arts has added to Origin a play time tracker. As can been seen in the screen shots below this can be found in the library when mousing over a game, or when in the game details screen.
Unfortunately it does not seem that the Origin client has been tracking the time all along, as those play time numbers are a little light in my case.
