Does this package contain something the previous individual purchasable games didn't?

more versions, a tradeshow demo, art n stuff

First of all, these are not the DOS versions, but the Sega versions of the games (also a Nintendo version of the lion king)

There are a lot of making of videos, mostly of the lion king, some sketch books and so on, full lenght playthrough video, soundtrack.

With a lot of research you can probably find most of it on the internet (where the gameplay videos are easy to find), here you get quite a good collection of them.

This collection is not so much about the games themselves, but about the nice launcher, the extras.

I would not have bought it, if I DIDN'T own the DOS versions. Only the discount makes it worth it in my opinion.

edit: Actually the terms "Sega" an "Nintendo" might not be that accurate, it seems they took one version of each console TYPE (handheld / living room). The Amiga versions would also have been nice.
