I have been a wargamer since the mid '70s, have done playtesting for AH years ago [before the Hasbro Empire] on both board and PC games. Did a lot of work on ASL in the late '80s thru early 2000s, including a published article [currently in 'Out of the Attic'] on a 12-point facing/movement system for ASL. Also playtesting/editing for KE, CH, and others.
I am interested to see what bgdf has to offer, esp. in the way of continuation/republication of 'old' game designs, esp. AH/GDW/SPI.
