As far as I know, Blizzard has not put-up dl's for SC: Ghost unit models that can be used in WCIII.
Sorry if this is an invalid idea or anything, but, still, it'd be cool if Blizzard did.
I think they should. Some people really enjoy using custom models in their maps. But you have to remeber that using models takes up a lot of KB's, depending on the amount of polygons. I still remeber when the Protoss Zealot models was made....It was such a huge file. If memory serves me correctly it only left like 300kb's. I would have to say that the war3 scene is equal in both on-line and offline gameplay. Offline games use a lot of stuff and it allows makers to create a map with any size (kb's or mb's) so I think it would be a great idea for them to do it. Although, if blizzard didn't do it for sc units then I don't think they acctually would do it.
They wont do it. If you can put it into W3, you can most likely recreate the entire game in a W3 map...
I'm not asking whether it sounds like they're going to do it or not, just if it would be something SEN ppl would like.
