Good activities for christian youth group?

Im part of a youth group in my church, and it ranges from 13-17, its a nice peaceful youth group, but i feel like everyone needs to be a little more open. i want them to show their opinions, to express themselves , i DONT want GAMES, i want activities. Lately we've only been talking about the bible, and that's great but i want something more... im thinking about doing the 'line game' where you ask a question and if that question applies to you then you have to step on the line, i want to ask happy fun questions but also serious questions like 'have you ever doubted god' ?.. i want activities like those. Any suggestions ?
