Nobody seems to agree on much of anything when it comes to Vader Immortal II 🙂 However, longevity got a 5 mostly because it’s a $10 dollar episode, so the expectations aren’t that high, and because you can spar indefinitely in the dojo – which is, admittedly, a lot more fun than the dojo in Episode I. I can still see why you’d feel that way, the ‘game/experience/campaign’ is incredibly brief!
