I've been playing through it again recently. I noticed that once you're assigned the Rescue Tiffany mission, then go and speak to Savage's lab assistants, they then go on ad say things like "Oh, Tiffany is Gary's only child, the only one left in his family" and I think "OK, better not screw up then.

"
I also find it hilarious when, in one of the fights with Simons (I manage to meet him in Area 51 having evaded him in the ocean lab - it is funny to see him try and swim with a blue sword in his hand), I just switch on the Aggressive Defence aug (set to level 4) and move a little bit back, then watch Simons utter something like "I've looked forward to this for a long time" before he blows himself up with his own LAM.
Funny little moments, these.
I've also really appreciated the final Paris level, in Everett's mansion - having completed the game twice before, at that moment you can pick up small snippets of where the plot's going, small hints of the multiple choice ending. Plus the dialogue with Morpheus is still thought-provoking and interesting. And of course, "A BOMB!"
Interestingly, I also managed to find an augmentation upgrade canister in a whole concealed section of one of the maps, which I had never visited before in all the times I had played Deus Ex. Amazing game, this.
