Basic answer, not necesarelly.
I used to read as a hobby the Wookiepedia and also to have an accurate view from SW Universe. Then people from SW told me that almost all of that info was Legends XDD
I use to prefer Canon and updated material, but as I said in another posts, without alternative stories (from Legends or from our own imagination) would be PRETTY difficult to play roleplaying games.
So, knowledge is important if you want to fit in the "SW gaming essence" but again, do what do you feel more comfortable. If you don't feel good or don't like the general SW mood, or you just want to add things from other world you like just... I don't know... ¿digimon? XD just do it! There are thousands or even millions of planets in SW universe, so, feel free to add your personal touch to your games ![]()
Knowledge (canon or not) is a good reference to understand (or get confused XD) about Star Wars universe, but its only just that, a REFERENCE.
