Purpose : development of cross-platform games for mobile phones.
The main target : iOS (iPhone / iPad) and Android, support for Windows Phone 7, Symbian, Bada will be a big plus.
Task : the most rapid and convenient development of games, the price of the engine does not matter. Of the games, presumably 2D arcade, casual games. It should be possible to display ads, support multiplayer and integration with the Game Center (iOS) / OpenFeint, sharing in the social network. Access to the native API will be a big plus. A large number of 3rd Party Tools, plug-ins and developments accelerating the development process are also highly desirable.
At the moment there are two applicants: Corona SDK and Unity 3d . Both have pluses and minuses. Heard the development of 2D games on Unity requires quite a lot of effort, in return we get the desktop and web versions!
In general, the discs. Pros, cons, pitfalls. Perhaps there are still good analogs that I missed.
