I'm not simply trying to stir up trouble, but here's a question that will be much easier to deal with now, rather than a few years down the road.
It looks like for the foreseeable future, tablets and phones are going to make up an increasingly large percentage of the "computing devices" that people use. Whatever your OS or hardware preferences, one reasonably probable future is one in which less GPL-friendly App stores are the gatekeeper to a majority of tablets. Regular old computers, weather running *nix, Windows, or Os X, will probably become something of a niche.
If you want Terasology to be playable on iOS, or whatever else exists down, A GPL license alone probably doesn't cover that (though there are more than one informed opinions on that point). Personally, my motivation for making FOSS games is not to support a particular licensing scheme, but so that people can enjoy cool stuff that i helped make. Other people's motivations may differ, and i don't think anybody has grounds to criticize someone else for having a different motivation.
The thing about licenses, is the creator of code, art, whatever can release his work under multiple licenses, and allow use under any one of them.
So, the most above-board, and legally unquestionable thing to do (if you want to do something like this) would be to write up a contributors agreement that says something like, "I hereby release my contributions to Teresology under the GPL and license X. It may be included in an app store as long as it is free." (insert actual legalese here.) To contribute, newcomers would need to "sign" the contributors agreement.
The point of this is, that while it may be a little difficult to get the current batch of contributors to agree to additional distribution licenses, it will be practically impossible down a year or two down the road when various contributors have come and gone. That's the situation Wesnoth found itself in a while ago. Better to plan ahead.
