I would like to see some thought going into the books we get ie what will this actually benefit most people who play Traveller - ie does it allow them to design more things or does it enhance their role playing? Most people explore, adventure, solve mysteries, investigate, and trade etc. Like the campaign guide - that sounds very useful.
I want to see more adventures by far and not too complex either. I would like to see cheapish booklets (like the original D&D adventures) covering things like updated Safari Ship, Chamax Plague, Marooned etc - all the classic ones, but not just repeated, done in a new way. Not massive adventures that take years to read.
I would like to see safari rules/hunting/trapping, chargen for animal related careers, alien world exploration, flora&fauna, etc, as Ive mentioned elsewhere.
I would like to see miniature rules for combat and spaceships that use the core book rules but revise them for people like me who like to use miniatures.
I would perhaps like to see a book on alien threats in the universe such as zombies, vampire races, Gigers alien type creatures, Starship troopers type bugs, and alien hunters of men (Predator), planet attacking giant aliens and just downright mean aliens. Not everybody in the universe should be nice and friendly.
I would like to see a book on high Tech Level stuff such as laserswords, Star Trek matter transporters, better-than-jump 6 engines, advanced civilisations, etc, for those of us who would like to take Traveller into the far future.
I would like to see some attractive colour ship plans done at 15mm scale (unlike nearly all of them) of standard ships like liners/traders/transporters that actually would be used for miniature personal combat. Also some starport plans might be great for battles outside ships that have landed. Perhaps some sample alien terrain plans etc.
