I've been a premium member since its creation and I've always wanted a tier that would give me the following:
- Once a month live chat "hangout" with the crew. Get to actually talk to them about games in a casual and intimate setting - more than a call-in style show.
- Extended cuts, Deleted scenes, Quick looks that never made it, and so forth.
- Behind-the-scenes stuff like studio tours or other non-traditional "see the sausage being made" content. Remember these?
- A Quick-look-this-next type list where we can add games, via the database, and upvote them. Statuses they could mark the suggestions are "already exists", "Won't do", "Planned", "Released".
Those are the main things I could think of that would be worth having a higher priced membership. Maybe the last one is open to everyone and this tier has a special track or something.
