That is the G-Gee app manager associated games they offer from the "Echo Top Apps" shortcut on your device. When you go to the Echo by Kyocera site/Top Apps and click on any of those featured games (sonic, monkey balls, burn the rope, etc.) you are sent to the G-Gee site.
I have gone back and forth on the pros & cons on this third party plug-in/app manager. But I saw that it was native to Gingerbread this time so I thought I would give it more of a try. I think the concept, and the games, are OK. The manager loads at 6+ megs but all of the games are store on SD exclusively. So if you do like 4-5 games there is probably a positive trade off.
And I discovered one thing, if you install the G-Gee manager first and ask for all the games from within that app, the individual game short cuts never get added to the app drawer. Now this is a matter of personal preference, but I thought that was nice. If you want app drawer shortcuts, download the games from the site individually. This will create little 45~ k installs that launch the G-Gee manager.
Probably more information than you wanted to know, but the games are available now from the installed "Top Apps" shortcut.
