I'm not for or against the practice of Gold subs per se, I'm always subbed as a family membership and share the sub/gamepass ultimate across all family members, games and overall think it's solid value. On to my point, aren't there a few features that would get cut that the Xbox Live platform is based on? e.g.
- parental controls (as a parent knowing what, how long, with who and getting weekly reports emailed for all family members and their xbox activity is a godsend)
- anti-cheating
- clubs/friends
- party chat
- screens/clips sharing
- achievements/gamerscore
- LFG
- MMR/TrueSkill multiplayer matching
- privacy settings
- leaderboards
- SPOP sign-in/security (pretty rare for MS account to get hacked, really stable system)
Isn't it worth it just to have one gamertag ready to go on all games you install? I'd hate to register account after account with each game/publisher and a lose the ability to manage all my family members in one place across all games.
