Wow. That's a lot of space for one game.

I would say in terms of features it eclipses Halo Reach. The addition of Warzone in itself with the REQ system, weapons, vehicles, skins in huge in itself. It does lack some things from previous games, but makes it up pretty good. I do hope thise will all be included in Halo 6 from start, with Splitscreen!

OT: I think most developers have become lazy as storage capacity has increased. Optimization doesn´t seem to be a priority anymore and it should not be ok that a game in file size is 10 times bigger than most games from the generation before, as is the case with Halo 5.

If Forza Motorsports 6 where that big it would have twice as much content as it has now.

Holy shit. That's a lot of GB needed for that game. The witcher 3 is at 67.99 GB with all of the dlc downloaded. Most of my games are around 40 GB.

Cinematic experience takes space.

Super Mario Land would fit 2,725,000 times into that.

The singleplayer is on the disc and the multiplayer part has to be downloaded. The rest is patches.

Makes sense, so IF you don't have it connected to internet, you can play solo and thus won't need the MP content anyway.

It's a shame it wasn't all there on launch, reviews would have probably been more favorable overall.
I grew tired of the Multiplayer component early due to lack of content and moved onto other games, seems to be a common theme with games at the moment. :P

Good work on Microsoft's behalf though, hopefully they keep the development of it going even after Halo 6's release.

The PS3 Uncharteds had pre-rendered cutscenes, the NDC had in-engine cutscenes. High quality audio also takes a lot of space (and you need multiple language VA tracks). This is why Nintendo games rarely exceed 3 GB on the Wii U: they rarely have many cutscenes, rarely have much VA, and of course a lot of Nintendo's games lend themselves really well to using the same assets multiple places. In a game like Uncharted 4 or Halo 5 it would look really weird with the same houses or buildings or whatever, but in, say Super Mario you pretty much expect levels to be built out of the same blocks every time.

Actually no, Uncharted 4 Cutscenes are realtime in-engine, NDC cutscenes are not.

"Today we learned that Bluepoint Studio had to redo the cutcenes from Uncharted from scratch for The Nathan Drake Collection, but contrary to speculation from some, they actually won’t run in real time, as explained by Writer Josh Scherr during a livestream on Twitch.

Scherr clarified that making the cutscenes run in real time would require Bluepoint Studio to rewrite the game engine in order to do it, because Uncharted was never designed to have real time cutscenes.

According to Scherr it would have been a “herculean undertaking” for Bluepoint, and the collection would have been released three years from now if it was attempted."

While all of your points on why a game is big is valid, it doesn't mean the game HAS to be that big, and File Size should not be viewed as a good thing, or a measurement of content, value or workload.

Games are definitely larger then they need to be to produce a game of the same quality, because developers have been spoiled by the massive storage of the bluray, (see ps3 exclusives and their INSANE sizes.)
