I did a couple of tactical diagrams that appeared in the Warships PDF by Rich Baker, but that was the extent of my involvement with Alternity. However, Alternity was a huge influence on me and started me on the path to becoming a professional cartographer; the starship map in the Alternity Player's Handbook inspired me to try my hand at that sort of mapmaking, and Rob Lazzaretti's enthusiasm for my work encouraged me to continue. My earliest starship maps are very clearly influenced by that Alternity deck plan style.
