I never look at the equivalent number of games when I see a Snowie rollout. It 
may have been interesting in the past, when hand rollouts were performed, or 
before VR was introduced. Over the last couple of years I think VR has gained 
understanding and acceptance; it's a long time since I've heard anyone question 
it's effectiveness. If it's a lot of work to add, I wouldn't bother.

As you say, it's the SE & JSD that interest me.
