Nice ones

Keep em coming!
Mentioning Deus Ex reminds me of another one.
I remember after the first mission when I was exploring UNATCO HQ, I went into the ladies' bathroom and later on I got told off by the supervisor for misbehaving.
What I like about most of these is that the game doesn't try to show them off like little gimmicks, it just lets you play around until they happen. For instance, if Deus Ex was advertising all its options like that, the above scenario would probably result in a subtitle message saying something like "Misbehaving on UNATCO premises may incur warning or penalties from your supervisor". It just breaks the immersion when it explains everything and it makes you feel that the game is saying "look at all the wonderful optional little gimmicks I have coded for you". It's much better to let the game play out itself without the step by step guide to it all, isn't it?
