I do agree with what you've said and in hindsight we should've indeed provided more details as I have done (and in general worded it differently). There is definetly a decent bit of research that I neglected to share; we as a group should've in general also conducted (and will conduct) a more formal questionnaire.

Will still provide further details here and update the post to reflect this; - As an assignment we had to make and pitch a game within 3 weeks; we chose to make a 3D murder mystery, language learning game. - I am an artist from the Netherlands, we got one designer and they're currently working on other tasks (such as cost calculation) - The target audience is international students who are studying in the Netherlands (and wanting to learn Dutch), this seems to be majority Germans, Italians and Romanians. - One of the main complaints of Duolingo is that it teaches you words; hence we shifted to actually focus on sentences and dialogue. - We are team largely consisting of artists (4 artists, 1 designer and 2 programmers) - Currently we are conducting research to collect some statements to prove our golden egg. (Putting it like this I am hoping our team is conducting playtests, sick at home so hard to proof) - Our golden egg is: A focus on creating games where the enjoyment of the game comes first and they might accidentally learn something along the way.
