1. Will the other 3 profiles have to be child accounts? meaning 3 profiles won't be able to download or play DLC that is marked Mature
2. so these 3 profiles won't be able to rate or use any features on live
3. will these profiles be able to still download their own content and add Ms points using MS point cards bought at retail stores, etc.
4. Anything else I should know like what the 3 other profiles can't and can do
