Virtuous are the developers who ported Dark Souls Remastered and LA Noire to the Switch. Will be interesting to see what they can do when they're not porting a remaster of a PS3/360 era game. Though they did do the Starlink port. But Outer Worlds will be by far there most ambitious port to the Switch.

Other than Witcher 3 it might be the most ambitious port to date.

That's just outright wrong because most games during that generation didn't even exceed file sizes of 1.5 GB. And those that did, could have been reduced in size to make them fit on a single disc if two discs were not wanted.

The primary reason why Nintendo didn't get those PS2 exclusives is that Japanese developers at large were not interested in doing multiplatform releases, hence why the Xbox missed out on much of the same games. American and European publishers have had a multiplat approach since ages, but the only thing that could change the Japanese stance was the failure of the PS3. During 2007 and 2008 there was hardly any month without news that an exclusive in development for the PS3 was going to go multiplat.

When you look at games with lower development costs, exclusivity of Japanese games remained much longer and was common on the 3DS up until the end of its life. If it's financially feasible to develop for only a single platform, then that's still what Japanese developers prefer.

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.

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. 

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.

I think Obsidian has learned since then. Now, if only the Switch version would come complete on cart, and not be a Half-Cart Half-Download title.
