Q: Can we have a team with only GD/GGP/IGP/ISP students (take whatever single major from these 4)?
A: Yes, but we don't recommend it, your game will be a lot better if you combine people from several majors.
Q: Do we need to have a team at the start of the jam?
A: No, but we recommend it. We will see if there are teams that are still looking for team members at the start of the jam so we can make sure that everyone is part of a team.
