I believe the 1.3GB is for the cISO, but the main disk image is ~4.3GB.

I don't think the game uses a dual layered DVD.

You'd be surprised at how much dummy data is on these games. Wii Sports for example is ~300MB.

Very interesting, then. Nintendo can fit a lot of content out of relatively few assets

Yeah I have noticed that. They have many games that are fairly large content wise yet the disc image size is pretty small.

They are masters of space conservation.

"Boy I would prefer you not make post like this. Effort, man! Efffort!"

You don't bother to actually respond, and you're claiming I didn't make an effort?

It looked like you just couldn't counter the post, so try to dismiss it.

What do you call this typo-ridden monstrosity if not a response?

Point out the typos. And don't confuse an odd sentence flow for a typo.

....Why the Hell do you want me to point out typos in my own post?

I called a man a critical analysis instead of a critical analyst

I used "yuou"

I used "conjection" when I meant "conjecture". This examples are just eye-catching, rather than comprehensive.

What's the point of this exercise, exactly?

Oh you have no idea.  Brain Age is something crazy like 10 or 20 MB and will probably outsell any game that is ever put on a Blu-Ray disc.  Aside from a few crazy-giant games like Super Smash Bros. Brawl and Metroid Prime Trilogy, Nintendo makes the smallest games by a large margin.  A bigger game is more often a sign of sloppy programming than more content.  Only Nintendo and some wackos like Will Wright who understand the power of procedural generation really know how to minimize game size while maximizing options and fun.  Have you ever seen some of the stuff that the procedural indie guys can do in the demo scene?

Nintendo hides resources everywhere like crazy.  Even in the first Super Mario Bros., they used the same graphic for the cloud and the bush.  They just changed the color.  They're the kings of crazy shortcuts like that.  If you look at the list of the best selling games of all time, not only are the top 10 Nintendo games, but they're probably some of the smallest games made for their respective consoles.

Your whole post is very interesting as a read and makes me want to look up some figures, but:

Oh, I thought you were claiming my post had typos.

And it's still not a response, when you treat a key point as something I somehow wasn't supposed to type. That's a BS response.
