Hi.

My question is regarding the kind of connection that can be made within external databases:
 
Do I can keep some sort of Leaderboard somewhere on the web and make a game update it?
Reason to ask: The idea is use a "XNBded" xml file that the game can read containing the LB status.

Does MS allow the 360 games to download data packages than not from the own marketplace?
Reason to ask: Is not an update that the players need to pay for and it will change on the fly.

If MS don't allow such thing to be done externally... Is there some kind of service that you offer to do such thing?


Best wishes.

XBLIG games have no capability to connect to anything outside of XBLIG. You can take a look at this

For the Xbox 360 and XBLIG you cannot connect to anything externally. There are no options in that, no services and no way around it. If you have an update to the game you have to re-upload the game and move it through the playtest/peer review again. When a user plays your game (and they've previously purchased it) they will be notified an update is available and they can then choose to update.

There are no ways to currently to true leaderboards on XBLIG. There are no ways to currently do true downloadable content or add-ons.
