With a big long list of uninspiring Star Wars cartoons, this has become less of a thing. Rogue One has proven to me that you can work RPG characters into a story that really works. You can take something epic from the media and make it your own yet keep it in touch with the original.
I had a huge number of Star Wars figures when I was younger. Sadly using the old Palitoy figures (which I think are the same as the ones made by Kenner in the USA) probably would not be much use now. In the last Star Wars RPG I played, Lego figures were used a lot and I still have a lot of time for the idea of using Lego figures in games. These are not things that most people want to use in games.
As a Games Master that believes that games are better with figures, Star Wars has always been a bit of a pig. WEG sold a good range of figures produced by Grenadier (which passed over to Simtac another long since gone company). These sometimes turn up on eBay and I have about thirty stormtroopers. Whilst some do turn up on eBay they are greatly tied into the movies so getty a range of characters, especially for alien races, is a problem. They are also 25mm figures which would make them hard work to match these days.
