I decided to convert my game to software (I’m using Twine), and to pre-2000 D&D rules.
I’ve nearly finished character creation using the types found in OD&D (with a lot of common house rules such as maximum HP at first level). The game will also have (at least) Neanderthals, robots, Atlanteans and Western gunslingers as player-character options.
Doing it as software will mean I can send out copies over the net for free. So hopefully it will be easier and cheaper to get feedback and buzz.
