As for the computer idea, it could be quite ideal if it were to have the same 'In-game Computer' System as GTA IV had. For example, using an E-mail and keeping in contact with the other Students who live with you on the campus, you could reply with a 'positive' or 'negative' response to the email (like in GTA IV) and they could perhaps give you some 'Jobs' (Side-Missions) to do, like when Brucie messages Niko to steal a bike/car for the money and you can accept/deny these.
