A few really cool announcements from Google have come out of the Game Developers Conference this year. Some of those features include Game parameter management, Video recording and streaming from within a game APIs, and a new trial run feature.
The new trial run feature allows users to browse games and try some of them for up to 10 minutes without purchasing. The trial runs will be ads. The game can of course be downloaded in full once the 10 minute trial expires. The ads will appear on wifi.
