Tell me you didn't even click the link without telling me you didn't even click the link. If you had clicked the link you would have seen the different breakdowns, including the completionist section. The pages I linked have a ton of data you could look at, and none of it is difficult to interpret. Also, the fastest speedrun for both games is just under 20 hours for Final Fantasy XIII and just under 4 hours for Final Fantasy XIII-2. Final Fantasy XIII-2 is a shorter game, and I can find plenty of corroborating claims.
Final Fantasy XIII-2 is the better game, but it is 100% a shorter game. Provide me some source that disproves me if you'd like, but I can find a lot of corroborating claims and statistics to support the claims that Final Fantasy XIII is the longer game. This goes for speed runs and completionists.
How they implement cut scenes (pre-rendered vs. in-egine) isn't optimization. It's a design choice. The initial game was made for the PS3 and then ported to the Xbox 360. The travesty here wasn't how large the PS3 version was. It was that Microsoft didn't want to go with a blu-ray drive and pay Sony royalties on the drives and discs for their games. If the Xbox 360 had used blu-ray discs Final Fantasy XIII would have flawlessly worked on the Xbox 360. Instead, Sony was forced to whittle down their pristine PS3 version to something that would fit on multiple discs that were each around a tenth of the size of the PS3 blu-ray disc. The end result was a game that played in a worse resolution and with more artifacts than its blu-ray counterpart.
Final Fantasy XIII-2 was a smaller game (again, the facts are all there), and moving to in-engine cut scenes drastically reduced the file size. These two factors, combined with a more agressive compression method, are the reason Final Fantasy XIII-2 fit on a single disc, and even then it just barely fit. In 2011 the XGD3 format was introduced that increased the usable space on the DVD disc to 8.3 GB, and Final Fantasy XIII-2 was a total of 7.8 GB. Had this game came out in 2009 (like Final Fantasy XIII) it would have needed two discs still.
All this is you trying to prop up a wrong source and people who think the main story is not the main story.
The "main story" (going by Squares own words) in the game takes longer than FFXIII it's clear you never actually played XIII-2 or even tried to look at videos of it, the "speedrun" is also not for the mainstory but for the fake out ending, one of many. that has nothing to do with the main story.
All this to defend Square Enix having the optimization skills of a blind alcoholic back in 2009 lol. There's more to explore in FFXIII-2, there is more content in FFXIII-2 (which you said there wasn't which anyone who played both will laugh at,) all you did in XIII is run down hallways, have a somewhat bland grand pulse middle section which after you passed that to continue the story turned into more hallways. I don't see why you would think XIII has more content. You didn't even do anything at the theme park. XIII-2 actually HAS a theme park with things to do.
Yes it is optimization, there are better looking games with cutscenes on the PS3 than FFXIII that don't take up nearly as much space, what other possible explanation is there? Even the 360 version version is substantially less and is only moderately compressed and there's still about 3GBS of unused space. It's not, even with the cutscenes, a 39.5GB PS3 game, that's just a fact. Even people who broke down the file size of FFXIII said the size is bloated.
FFXIII-3 itself also was unoptimized and used similar engine and other tools as FFXIII, so even that game could have been shrunken down less and this is also obvious looking at other PS3 games, but I understand given the money spend on them Square would want to use them again instead of starting from scratch.
It's really just a case of Square Enix not being ready for next gen. Ask yourself this simple question, do you really believe there's enough in FFXIII to be bigger than MGS4? No.
This is very well known..... The sole reason it is exclusive is because of him. I don't understand why this info is "news"
And the excuse to not release it on Xbox 360 is a joke, the game install every act on PS3 it would be even quicker to change discs every act on Xbox that waiting 15 min installing each chapter, so yeah he is a fanboy.
I heard MGS4 rumors that the super slim makes the install times faster but I'm not going to by that cheap model and I can't find anyone who will test it.
