If I heard it right, all the objects in the game including the environment and background are 3D objects so I guess if you're really good at hacking you can change the game camera into a third person perspective instead of 2D view, and the level would actually look like a 3D platformer game.

And as mentioned earlier, uncompressed audio can take up a lot bytes, too.

Or maybe Retro just isn't as focused on being "efficient" as a lot of Nintendo's Japanese studios are? I think Nintendo's focus on digital has resulted in a lot of their studios making it a top priority to keep sizes down. Retro probably wasn't worried about that and as others have pointed out, between audio files and unique textures, that's likely the bulk of your 11GB right there. Not saying it won't be a fantastic game, but I certainly wouldn't go in expecting 9x as much content as Super Mario 3D World.

Wow, big file size for sure. Although this is retail game in my opinion.

Jungle still massive in 2014 confirmed.

"Back in my day, we didn't have any of these fancy Gigabytes! I did perfetly fine with under 50 KB!"

I know right? I was expecting a game that is at least 20 times bigger than 3D World! Retro has to get their shit together or I will stop buying their games.

I thought this was said a while ago

Looks like I will be getting the retail version

Have you ever used WinRar or 7zip? Before you extract the file, that's what's called a compressed file. When you extract those files, it is uncompressed. Compressed files are smaller in size.

This isn't exactly the same as what developers do with game files, but you get the idea.

we all know that.you dont need to proove it
