Are you doing box sets or army packs?
What about rule system?
At the moment it will just be Unit Packs, 6 suits per pack or 1 Walker per pack.
As for the Rules, we will be sharing the old SF:3D rules and our own modified version of the board game. Mike and I have been discussing making some official S2G made rules, but its not looking too promising. I have spoken to Robin Fitton as to having cards made for the various units to fit into his Gruntz game, so there will be other options.
