Can I play online multiplayer games in Romania

Xbox Live (now called Xbox Network) is the service that connects the console to online services, which includes online multiplayer. You also need a Gold subscription to play those games online. Since Romania is not supported, Gold is not available there so you wouldn't be able to play online.

There haven't been any announcements on when/if the service will be available there.

Thank you so much for the quick response! I really appreciate it. That's a real bummer though since Romania is an EU country I would think it would be an easy transition. That's a real bummer. Do you possibly know if Xbox Network is going to be rolled out to Romania soon?

Unfortunately Romania is not supported for xbox live at the moment.

You will not be able to get online, purchase digital games, redeem codes or play online multiplayer in that country.

Changing your region will not fix this. Sorry.

I'm sorry but Xbox consoles are not sold officially in Romania and as such access to any and all online services including the store and multiplayer are not available
