A lot of fun. The only cons are it’s pretty short (all three eps combine for 2 hours or so), and there’s not a ton of combat.
As for the pros…if you’re a Star Wars fan you need to play it. If you watched Rogue One and thought “damn Vader’s castle looks cool. I wish I could wander around that place” well you’re in luck. Lastly there are moments (jumping into hyperspace and feeling like you’re there, having Vader right in front of you staring down, etc.) that are worth the price of admission and then some.
