i am currently working on a project like this now, and you might be wondering: "intro levels? what are you, do you have some obsession over intro/outro levels?" Well, of course i do. intro/outro levels always looked like a different breed or a branch off the run of the mill normal levels. they felt so interesting and magical IMO. And it really does a good job giving out a first impression to new SMBX people; so why not host a big pack of levels you can use for your own personal purpose, or heck, even MAKE it yourself? I said myself.
