Now, i have seen the movies. some of them multiple times. I also read a bunch of the books....30+ years ago. But I have not read all of the books or any of the newer ones or watched the cartoon series and whatnot so i am "behind the times".
But looking at a different thread about making new ties I had a thought. They have pretty much done all of the official variations. Possibly one or two they have done are not represented here but to me it kind of looked like a bunch of spitball oddball ideas hoping someone would like it so that they could make the claim of "inventing" the tie. Now, I see the possibility of making a few new ones for us to play with here for first order and early prototype versions for the empire (because they could have been in development at that time but not in general use.
But, right now, pretty much everyone that is not part of the rebellion/resistance/empire/first order official army are all just lumped together under scum and villainy. I feel that this could easily be broken down into mini-factions that while they are not a major part of the movies common sense says are part of the "mythos". For example, the cartels. The mining guilds, the other corporations. ****, there are even areas where the empire is only a legend that happened elsewhere. Even in the more recent movie they made a big point of the weapons/ships sellers selling to both sides and how many thought that they were the truly evil ones (I can see them taking this somewhere or I dont think they would have made such a big production of this)
There are enough models already to represent many of these and depending on the different "group" or force being represented, they would naturally have access or would gravitate towards different combinations of ships that we already have and the only thing they would "need" is like a single ship dedicated to them solely for flavor and the rest would be a ready made faction with what we already have. Each "list" could have different strengths and weaknesses depending on the specific rules that apply. A cartel would have more contraband and smaller ships while a mining guild would gravitate towards bombers, freighters and only a few dog fighters. A corporation would have the most expensive and elite ships. All in how the list makers wanted to represent them. With a single wave release of4-5 ships, 4-5 entirely "new" complete factions with all ships could be put on the line. without having to add the extra shelf space or production just selling more of the ones already being produced. Could also draw in many more new players.
Thats just a broad overview but I'm sure you get the point.
Models. Notice that i mentioned many of the ships we already have would be used in different combinations with those lists.
Would unpainted ships be an idea? This I am not sure of because a person could just as easily paint ones already done up. Along witha variety of "official color schemes for the more established set groups and folks being able to "invent" thier own smaller ones ? This last just random thoughts.
