A few game titles that never did end up happening, but which almost did. Or did. 

Star Strike

When I was working on Clash on the Fringe, my wife and I came up with a list of 50ish names and ended up picking this one, only to realize that it was actually the name of an RPG supplement (for SpaceMaster I believe).

Only the Dead

Working title for the very first draft of what became No End in Sight. It was a reference to the quote that "only the dead have seen the end of war". I ended up changing it because it made it sound like a zombie game.

Afghan Soda Can

A little experiment in modern day squad combat, heavily inspired by some video game I played. I don't think it was ever particularly playable and I don't think a copy survives.

Laserstorm

This one got published but the original draft was actually intended for squads of single-based 15mm figures instead of 6mm team stands. 

Dungeonhack

A dungeon duel game with a bunch of different character classes that all had different abilities. At the time, I realized I did not want to write a competitive game and it got shelved. 

Monsterslayer

A solo fantasy game inspired by the Demons Souls video game. It was kind of a repetitive grind but probably influenced some of what would become Five Leagues later on.
