The following info may not be entirely correct, but it is about as close as I'm going to get without downloading a bunch of emulator files. If somebody could post official file sizes from an emulator site, I'd appreciate it. For now I'll just serve this up as a mostly correct example. 

3.27 GB - Arc The Lad Twilight of the Spirits
2.06 GB - Atelier Iris 3
2.46 GB - Devil may Cry 1
4.08 GB - Devil may Cry 3 SE

Xbox missed out on so many of the same games, because Xbox pretty much didn't exist in Japan, and only sold something like 25 million worldwide. 

Gamecube's mini disk sizes had another effect on games though. People bought a PS2 because it could play DVDs. The mini-disk made it pretty much impossible to play DVDs on GC. That in turn hurt GC sales, which hurt 3rd party support. Had the GC sold 40 million instead it might have gotten more of those 3rd party PS2 exclusives. 

Atelier Iris 3 was a real beast.

But seriously, when there are 4.7 GB of space available, developers simply don't care to reduce the file size, especially when there are never any plans to port to the GC to begin with.

There's a thing called the Panasonic Q which was a GC with the ability to play DVDs. It sold much worse than the Xbox in Japan.

By the way, you are acting oddly forgiving for the Xbox. In your first post you mentioned Xbox third party exclusives and then pointed out that they weren't exclusives because they were ported from the PC. In the recent post you excuse the Xbox's lack of games with its low sales, but apparently that didn't matter for the GC. Instead you try to put the blame for low GC sales on its storage medium. You've hung out too much in PS-centric forums if you believe that the storage medium has that much importance. It's not an uncommon belief; after all, the vast majority believes that the Nintendo 64 would have gotten Final Fantasy VII if it had used CDs as storage medium, but the reality is that Sony paid off Squaresoft and that would have happened regardless of the storage medium that the Nintendo 64 used.

Legend11 correctly predicted that GTA IV (360+PS3) would outsell SSBB. I was wrong.
