The company behind FarmVille, Mafia Wars, CityVille (and perhaps the death of PC gaming) may be going public this week, valued as high as $20 billion, Reuters reports.

A source familiar with the initial public offering tells Reuters that Zynga plans to raise $1.5 billion to $2 billion and could file paperwork as early as Wednesday. The IPO, the source said, could value the company as high as $15 billion to $20 billion.

On analyst put Zunga's annual revenue at about $1 billion. PopCap Games told Reuters earlier this year it plans to file it's own IPO by the end of the summer.

The risk to investors is that Zynga's games, all Facebook games, could see a sudden shift in interest by a fickle group of users who aren't as invested in the franchise or gaming as a whole, as traditional gamers might be.
