There's been a fair amount of chatter recently about Namaste's upcoming game/system, Storybricks. The tech they are talking about looks very cool.
But here's the problem I have with these types of games:
Where is the audience?
Creators need an audience for their work. A writer needs readers. A director needs movie-goers. A machinima maker needs YouTube viewers. And a game designer needs players.
So what is the hook that will get people that will play the stories that others make with Storybricks?
When I think of the most robust add-on/amateur communities, they tend to be for games which stand on their own, which throw in mod-tools as more of an extra than anything else. Quake, Civ mods, the WoW mod community.
And I don't think this is coincidence. I think that the audience, that group of non-creators, is essential to the growth of a creator community. It provides the feedback loop and the sense that people are using your creation because it is useful or provides enjoyment.
This is the part where the creator-centric or building games always seem to stumble for me. I just don't see what will draw the audience. And without the audience, I don't think a creator-centric game can thrive.
