So When my XBOX Live Gold promo ends after 1 month and my account becomes Silver.

I will lose:

1) The ability to play all games online, or is it dependant upon the content and/or the game.

2) Would that include XBLA games?

and 3) what else?

I think the gamerscore card stays in-tact with the achievements.  Is that notion correct as well.

Thanks for the Help!

 

1. Correct. XBL Gold allows for online play.

2. Correct. XBLA games need Gold as well to be played online.

3. I think that's "about it". You do have to wait an extra week for demo downlodas on new games, but I don't think there's much else.
