Not entirely sure if this classifies but I think MGS2, 3 and 4 all suffer from this. They're awesome games, but I can't help but feel like every instalment made things more and more complicated while they didn't have to be. Why was the auto-aim on the Socom in 1 not good enough for the others? Now we have to actually stop moving, switch camera angles (this especially confuses me), aim and then fire to take an enemy out. I remember 3 to be especially slow because of this, and 4 had just too many moves to make any of them practical. All of that turns the legendary skillful solid snake into one very clumsy rookie in my hands and totally breaks immersion imho.
