Take-Two Interactive (TTWO -6.67%) should be worth at least $2 billion in market value, Fool contributor Tim Beyers says in the following video.

Why? Grand Theft Auto V is much more than a single-player game. An accompanying online world promises expansive, multiplayer experiences to those who buy the game. Players have already started logging in, putting pressure on Take-Two's servers. Over time, the revenue from GTA V online could double the game's $1 billion sales haul, Tim says.

In the meantime, Take-Two stock trades for just $1.7 billion in market cap. Tim says that's lowballing the potential of the company's signature franchise. Do you agree? Disagree? Please watch the video to get Tim's full take and then leave a comment to let us know where you stand.
