What is Delta Vee? It is the technical term for change in velocity, often used in rocket equations to denote the maximum velocity the rocket can obtain from a standing start. It is also the name I gave to a space wargame I first wrote back in 1995 or so, before I started using Full Thrust. I've recently decided to start reworking the Delta Vee rules and make them public.
The primary design goals for Delta Vee are to provide a scalable, simple, hard sf framework for modelling space combat.
It should be able to scale from small fighters up to craft such as the Lexx or Sleeper Service. By scale, I mean that the same battle should be able to cope with small craft fighting big craft, rather than using an undefined size that can be set for different genre.
Reasonably simple and fast. Warhammer/FT style of throws lots of dice rather than looking up charts and using hit locations (e.g. B5 Wars).
Must use vectors for movement and reaction drives, so keeping track of reaction mass is very important (hence the name of the game). Must still be simple though, but how to do this was all worked out 10 years ago, so I can use the old rules.
