tfishell: Maybe but in that case it makes me wonder why GOG couldn't just bundle those files with ScummVM and have the game as a bonus with the remaster to let people avoid the extra work. And that way we could complete the wishlist entry, too. :P
Sir_Kill_A_Lot: One reason could be that GOG would have to support the game with an additional engine (ScummVM).
Or maybe the publisher doesn't want it or licensing doesn't allow it.
But as long as I can get the original version and download ScummVM myself I'm happy!
I don't know anything for a fact, but presumably it's because of Disney policies.
They don't include original files with Monkey Island games either. Doing it with Double Fine games would be even more complicated, because (presumably) stores like GOG make a deal with Double Fine for a Double Fine product, so adding a Disney-owned product as a bonus (even if it's the same game) would be too complicated.
Companies with more relaxed policies, like Revolution with Broken Sword, don't seem to have any issues with those original files being a bonus.
Then again, Revolution is probably the worst possible point to compare anything with, as they are just too nice (releasing older titles as freeware, doing free giveaways, giving Kickstarter backers codes to all stores/platforms, allowing fan games like Broken Sword 2.5 to exist, etc. etc.)
