Well, I like the idea of education. I think it's a virtue. And just... for rather silly reasons related to a game some friends and I once played together, early on I had wanted to unlock the church, but obviously Poland claimed that building, and so I agreed to unlock the school instead. It would be nice to keep that promise.

Finally, I think that if there are guns in the gallery, then it would be better not to unlock it - as those would end this game sooner.
