Activision Blizzard (NASDAQ: ATVI) sold $1 billion worth of its new console game, Call of Duty: Ghosts, on day one! Except that it didn't. The gaming giant's reported figures only included the value of units shipped to retailers rather than titles sold to customers.

How should investors respond? Fool analysts Tim Beyers and Nathan Alderman advise a closer look at Take-Two Interactive (NASDAQ:TTWO) in the pilot episode of Geekstock, The Motley Fool's new web show, in which we talk about the big-money names behind your favorite movies, toys, video games, comics, and more.

Tim says using the sell-in rather sell-through numbers obscures the real earnings power of Ghosts, which, while likely to be considerable, is also probably well short of the $800 million Grand Theft Auto V earned on its first day in stores. Nathan adds that the Call of Duty franchise is beginning to get long in the tooth, and that Ghosts may not be much of a refresh.
