After playing Episode 1 of Back to the Future:  The Game, the next day I spent a few minutes walking around at work telling some co-workers who I know love the BttF films that, even though I know they don't play games, they should absolutely give this a shot.  A few of them said they would, some of them said they even heard about the game through mainstream press and were already thinking about trying it.  I realized later that out of the hundreds of games I've played, this is the first time I've ever bothered suggesting a game to those who don't normally play them.   
 
Anybody else have a similar experience with BttF, or maybe another game?

Poker Night At The Inventory (Hey, another Telltale game), and a lot of apps.

Steel Battalion. I think I indirectly accounted for 50% of its sales.

I have no friends that don't play games.
