In our office we have me: a person who loved Skyrim but struggled to get into Fallout 3 for some reason. We also have Luke Hopewell, Gizmodo Editor. He loved Fallout 3 more than any other game ever made, but couldn't get into Skyrim.
Now I'm not saying that you can't like one and not the other -- both games are similar -- but people tend to prefer one over the other. Which is your favourite?
