recently me and a friend have been faced with the issue of designing a basic simulation that lets 30 or so people interact with a text based simulation that lets people roll dice for specific effects to happen within the game that effects everyone and also,sadly, it must run on a Mac OS X, we have access to the school server and this is one of the last chances i have to find a program that will help to design such a simulation.
Just make a web program. As long as they all have browsers, your fine. Writing cross platform software is a difficult task so avoid it by just making the thing in php or asp.
ok i could probably manage that but the only web design experience i have is using HTML and some JavaScript, how would i go about doing php or asp, heard of them but never used
