One of the things that makes me love the original Star Wars movies is the sheer amount of detail in them. The places you visit feel like they could really exist, and have really been lived in. One scene that always stood out for me was when R2-D2 and Chewie play Holochess. It's not vital to the plot, and the game doesn't make another appearance until The Force Awakens. However, it gives us an idea of what people do for fun in the Star Wars universe, and allows for a bit of character development.
