Re: How to Start PVZ Garden Warfare on an Xbox 360

An Origin account is required to play and is seperate from the Xbox live account. The email used does not have to be the same, but should have a seperate password for security reasons.

From my general understanding for underage accounts it would like the child origin account to be linked to a parent's Origin account or something along those lines.

Since I'm not familiar with child accounts, it may be best that you contact Customer Support: http://help.ea.com/
