Dear Mr / Mrs,
I am a student in Translation from the University of Mons in Belgium. I recently discovered your game entitled Missing Stars, and I would like to use it for my thesis. Indeed, my thesis will consist on translating and localising a videogame from English to French, which is my mother tongue. Thus, I would like to ask you your permission to work on this game. I will use it only for an academic purpose, which means that I do not intend to commercialise it in any way.
I hope this message will find you well, and I hope to get your approval soon.
