We are in!
This is the first time in more than a dozen jams that a theme I wanted has won, so I'm very eager to get started as soon as my cousin gets here!
I made up some ideas for all the themes during final theme voting and we're probably going to try and execute some form of a FPS Collectable Card Game (debate on how exactly to commence soon).
We'll be using Unity as that's what we're most comfortable with and are very likely to use pre-made assets from the Unity Asset Store and opt-out of Graphics, because we don't have a lot of experience with 3D.
We're having a little get-together at the office for the first day of the jam with a handful of people hopefully coming to join us for day 1, so we might end up picking up additional recruits if anybody lacks a team or an idea.
