[closed] Best-Practise to use osm-data in games

Is there really a way to use osm-data in games that comply the odbl?

I will try to play this through using the example of a "virtual" game:"Simcity OSM" and Mark questions with Qn:

Let's say the game should use only street,river and rail-data and the task of the game would be to build up a new city based on the given osm-data.

Workflow: 1) I build a converter that takes osm-data and produces the reduced data (filtering streets,rails,rivers and mapping to my own coordinate-system). Since this already is a derivate this data is under odbl again. There seems to be two options:

a)provide the data as data-files

b)provide the converter that produces the filtered data in readable-form (e.g. xml)

Q1) Is that right understood? If choosing b) The game itself can use a proprietary version of that data?

2) The game reads the data as created by the converter, meaning that I have something like a "live-version" of my new odbl derivate. When I now build a house at coordinate x/y I would have changed the database-again, meaning this need to be provided somehow!?

Q2) Creating this live "fantasy-data" still creates a derivate, right? So would a live-export-function be ok, sufficent or even not necessary? (Actually it sounds like a quite cool idea :D)

Q3) If there would be this "live-data" option, would be providing the converter still be necessary?

3) Of course inside the game it is mentioned (in the credits!?) that the data is a derivate of osm.

Conclusion: To be honest, while writing this, I don't see a problem anymore, as there wouldn't be a problem for me to provide something like "live-views" of the data. But it would be nice to hear some comments if I'm right, about the way to handle the data!?
