You could make it a selection for the player, they choose one then the other is destroyed in a comically horrific manner. The narrator could berate the player for so callously destroying the unchosen duck who clearly has a deep and tragic back story and has long lost relatives who will sorely miss them. The duck you choose may turn out evil or maybe somehow the worst, just an awful duck who you should not have saved. The Duck Linked Content could be an included DLC.
Half Life 2, I got a new laptop a couple of years ago and it was the first that could actually play it properly but I never got to it, then the big update came out and wow, so worth it, loving it.
TES IV Oblivion. Love it, so silly, I love thieving.
Autonauts vs Piratebots, such a fun and cute little programming game.
