Hi,
along with what you have I also have 2 At-Ats, 1 official At-St, the 9 At-St Models from last year. several Snow speeder models the 2 AT-Ats that we used last year. Tones of Rebels and imperials.
We agree with you that the planning should start now if not soon. I am willing to let you take the lead on this with the blessings of Tom and Mark who run the War Gaming room. Contact me privately and we can start to bounce Ideas off each other.
To reach me privately you can use the forums to send a message to me. and we can go from there.
Thanks
Tiny
