So I finished Portal 2 on Wednesday night and ever since then I cannot stop thinking about it. The whole relationship with GlaDOS and Chell, Cave Johnson, Caroline it all made me just, kinda sad.  
The game has left me sad like no other game did before. The whole thing that it´s implied that Chell is Cave´s and Caroline´s daughter in combination with the two songs at the end just kinda got to me.  
 
Does anybody else feel this way?

I think how it's absolutely incredible how Valve can achieve such amazing levels of player immersion with such a limited amount of direct narrative.
