Video Game Source
 

What's the go-to source for the names of video games, like how IMDb is for movies and TV? For example, I was trying to figure out what the definitive name for "Civil War: A Nation Divided," but Wikipedia, ESRB, and even the developer had conflicting titles. (And yes, I checked IMDb, it wasn't there.)

I personally rely on the website of a German gaming magazine for titles.

I would've thought ESRB or PEGI, but for the Civil War game, the closest thing ESRB had is "The History Channel Civil War" which has to be wrong. (PEGI didn't have it at all, I'm guessing they didn't bother to release it overseas.) They're right about most other things though.

I'd check the big names (Gamespot, IGN, etc) and go with the most-used name. For a tiebreak maybe see what they're called on Steam or Amazon if you can find them there.
