One of my favorite multiplayer experiences was in Jedi Outcast. The combat had so many aspects to it lightsabers, guns of all sorts, varied force abilities, different map types. Its still one of my favorite games.
Biggest game world could hard to determine. What if you had a world like skyrim's but shrunk the character. Does that make the game world "bigger"? Point being size, at least in video games, is relative .
