Yes this is one way: games are very useful for dissemination and community consolidation.
But it could also happen that, if we have the right team, they can create something similar to CriticalCity Upload o Basilicata Border Games, using IoT system or other networks, in that case, is the game itself that create a community around a theme and can explore it creatively.
There are 2 big difference between the two ways:
1) budget, the first is one design / one shot, the second is based on time i.e. people working on it.
2) the first is a game where space and time are limited, the second is a pervasive game ie a community that needs what community needs, energy, management, care etc..
And I agree, for my previous experiences, that the second needs a more robust and committed involvement, design and budget wise.
