Some isometric fantasy action/adventure stuff (sort of a smaller "Landstalker", but maybe going a bit of a different way in order to make sure the task is not too big) would be neat and in this case I would be highly interested.

But in order to join soemthing there has to be a well laid out plan which shows me that this is - unlike many other communtiy projects - is going somewhere.
also my availability is quite irregular, but I'd like to improve my skills concerning team work.

I expect at least SVN, Doxygen, a bug tracking tool and clear assignments/requirements. I'd also appreciate some general coding rules concerning module interfaces. This way I see it possible to distribute the work properly and this might indeed work out.
