How to build the backend for a turn-based multi-player game?

Does anyone have any experience building a backend server to support a turn-based multiplayer game? If so, any recommendations for building a server app? Would it be better to use PHP or Python/Google App Engine or something else? What would interface with Corona best at the moment?

You’d have to have basic account creation and game matching features.

Any thoughts? [import]uid: 1560 topic_id: 4738 reply_id: 304738[/import]
