Games came out later. If I remember correctly it was released as more of a stop-gap version to get games-specific fixes out sooner than the regular release cycle.

From Wikipedia (http://en.wikipedia.org/wiki/CrossOver):

* The difference with regular CrossOver is that CrossOver Games will have a shorter release cycle in order to update faster to the latest work on Wine than with regular CrossOver, which targets stability and reliability.

* Crossover Mac was divided into Standard and Pro versions like Crossover Linux. The standard version includes 6 months of support and upgrades, while the Pro version includes 1 year of support and upgrades and a free copy of Crossover Games.

according to TUAW:

"Word from CodeWeavers execs is that the free license will be for a download-only flavor of the Pro version (!), including the Games optimized build and the option to share a Windows 'bottle' among multiple users on the same machine."

games is 2 megabytes larger. it must be better!

just get both, their fault for bad UI.
