I think it will be a great idea for The Sims Mobile team to live stream on twitch.
They should live stream for events or updates and interact with players and fans in real time. It's will be great to be transparent about events and maybe give a short walk through and show new items!
Most of the sims gurus on the sims mobile are on twitter but not as known as the PC sim gurus except a few who transfer over to mobile. It will be great if a lot of people get to know who they are and what it's like to work on a mobile game.
