GenCan't includes different contests and and articles and even a few game days at game stores that aren't in Indianapolis. But what really led me there was this year's Roll and Write contest, which gave me access to over thirty Roll and Write PnP games.
Which, frankly, is quite the bonanza.
Really, when you think about it, if you are going to have a PnP contest where the games are accessible for the largest audience, this is the way to do it. No construction, just print and add dice and pencils. And it looks like the designers really explored a lot of different ideas and mechanics.
As of my writing this, they are still adding games to their library, presumably as the designers give the site permission. And we haven't even gotten the actual winner yet. Fun!
While the Roll-and-Write library is my biggest interest in GenCan't, the whole idea of it is neat. Let's face it, a lot of us can't go to GenCon. The site creates a fun sense of solidarity, one that is even international.
