So, you finished it...Wheatley is awesome, right? He was the star of Portal 2 afaic. But the entire game is so polished, so well-designed...I found it hard to find a fault with it (like I said yesterday). It's still GOTY 2011 for me, edging out Witcher 2. The ending (turret opera) was a really fitting epilogue, and I liked the whole 'origins' storyline - Cave Johnson and his crazy plans and demise - a lot too. The goo parts were probably the high points of the game for me.

I don't know if you tried it, but sometimes when Glados or Wheatley are telling you to do something, you can just refuse it and they'll react to that - often with reams of additional dialogue. When Wheatley turns 'evil' the best parts are when he tells you to kill yourself. One part, he tries to crush you and you run away and he'll yell 'come back!!'. If you DO stop and go back, he'll go 'oh you came back...well uhm I didn't really plan for this. Why don't you, erh, jump into that bottomless pit right here?'. If you do THAT, you'll hear him say something like 'oh well that was easier than I expected. Didn't think you'd do that, but great!' as you fall to your death.

There are so many similar 'hidden' jokes in the game, it's worth testing them out.

BTW, loved the moon, even though it was insane and violates the laws of physics something fierce.
