The newer the games get, the less solid they feel in general. Like Tommy and sttng feel heavier than the Sterns I have when it comes to shaking them. Weight and feel have no real bearing on fun and challenge factor though. Frankly, I'm glad that they're a little lighter now, easier to shake, easier to move. Trying to move games like sttng and Stargate will kill you, lol. I would agree with the above poster that IM is one of the lightest games I've played, but ironically it's also one of funnest games I've ever played...a case where less is more.
