Sentinels of the Multiverse - seriously, you should check it out. The joy of defeating a nefarious villain with your fellow heroes is impressive, as the game pulls you right into a story out of a comic book. It's (thankfully) not collectible, but each hero has a completely different feel and flavor. It's become the go-to casual game for our gatherings since we picked it up at GenCon last year. (And now I need to go look for more dice to contribute to your collection. Gave you all the good ones with stories behind them last time... ;-)

Very glad to hear!
