I just played through this game, is there a lot of content that unlocks after beating it. I played on jedi master my first playthrough and explored basically 95% of everything. Didnt see a reason to play after minus the new lightsaber colors.
I played at launch and wanted to replay for the anniversary. My first game I spent around 45 hours to collect what I wanted and then have been using my second save to get the collectibles I didn’t get the first run.
