The huge advantage with using multiple projects at the same time is you can trivially factor out mutual pieces of code and include them as libraries. It's a really important thing for extremely integrated large projects that have big overarching goals. For instance the game I'm writing as a server and a client. The idea of the networking components are abstracted away from the server and client. They include a library all together that handles everything. They don't need their own implementations and I don't need to switch back and forth in the IDEs to get to the right projects, start them, compile the library project, and go back to each sub-project and include it. It's so much nicer when working on client-server architectures. That's why I love eclipse
