Alright, thanks again. I simply made a poll on our facebook page presenting them with the question of what motivates them and giving them some options (might not be the most subtle way to present this, but im just going to play open card with them). Will probably take it up with each of them individually afterwards. Good advice!

Thanks for all the replies!
I will try a different approach. Although it wont be easy. Today for example we had a meeting planned, one of the older students who works besides his studies even took a day off just so he could come to the meeting (announced the date a week ahead). In the end, out of 9 people, only me and him show up. As friends my classmates are awesome, but as working partners...its hard. They all said they would commit to this project, and then after today, its disrespectful towards the guy who took a day off for this (although i have to admit we did more work as when we would have with
9 people around a table). If i can make them realize that this is our project as a team (not just my project) and that we are doing this because of a dream to someday have a fully functional game (or whatever motivates them!)..and approach them as friend and not as project leader..ah well, lets try it, nothing to lose. And of course reminding them of the progress we make from week to week is a awesome idea!
Out of the 9 people i know at least 3 are really committed to this project, but perhaps that is enough to make a prototype of the game (in worse case scenario).
