I'm almost always disappointed with museum, gallery, painting... content and environment. As if video game was a child in search of legitimacy which have to use some formal conventions that don't fit to it. Here is a good surprise ! You use it as a pedagogical experience gathering datas, reflexions around your theme and bring us interesting questions : that's what exhibitions are for ! I think your going well with this creation. For now it proposes a self-explanation of the genre that lead to the "gaming" experience, I hope you will find the right way to shape this route cause it could be such a great one ! ( btw, sorry for my english, i'm french :D . Also I didn't encounter any performance trouble.)
