The success of Unreal Tournament was to develop a game graphics engine that was really versatile, so versatile was this engine that have licensed other companies to create games based on Unreal Engine.
It is a huge benefit for developers because they do not have to start building the game from scratch. This saves considerable resources for any game that can be spent on improving other aspects, thus creating more impressive games.

Works with OpenGL ES 2.0 at the iPhone and iPhone 3G will not be compatible with these new games, but despite this setback, adding many benefits: more powerful graphics in games, less development time, ie games are released before the investment in saving time and money. We are eager to try new games built on this engine.
