So in Starcraft II: Wings of Liberty there's two points where you have to choose which plot branches you want to follow. This only actually changes a few things, like four cutscenes and two missions total. (There is a third choice later, but that doesn't affect the plot; just whether you'll face Nydus Worms or Mutalisks in the final battle)

Naturally, the moron that I am, I chose the wrong ones on my first playthrough! The choices I eschewed are, in both cases, way better than the ones I chose, from a story and character development perspective.
