ODST sold over 6m... And Reach and 4 sold well over 9 million... What do you quantify as huge sales?

If Halo is not the biggest IP MS had what it's the biggest IP Microsoft had.Reach boosted xbox360 sale by 100k.

The name alone will make the game sale no matter how bad the game is,and MCC will have no effect on Halo 5 .Halo is bigger then Titan fall so not everybody who is interested in this kind of  gameplay  have an XB1。

Halo 3 sold 12 million units up until now, but no Halo game released after that pushed numbers higher than that.

The games released after Halo 3 weren't system sellers by themselves, rather Halo 3 and a combination of releases made their sales happen.

As far as the "huge sales" comment I was talking about single games and their ability to move hardware. If a game by itself moves multiple millions of units of a console by itself, that's a huge system seller. Halo 3 being the biggest seller and 1st Halo game on Xbox 360 was the system seller, the subsequent releases did well because of Halo 3 and said subsequent games both being on the system.

Halo 5 will be the Halo 3 of this generation, but I doubt it's going to be close to Halo 3 for units sold or have the same kind of effect on hardware sales as Halo 3 did for the 360.

In the past I had to have a 360 because I wanted to play Halo 3, but I decided to wait until more games were out, this generation I can gladly wait until other games are released for the XB1 before I will be willing to get one.

Only the die hards are the ones that must jump to buying the system because Halo releases on it.

Just like me most people will wait until there is a library of content they want, to make the investment in the platform worthwhile, a single £40-$60 game, with a campaign I'll play through once and a multiplayer I won't touch isn't enough for me to buy the system. Most people think about the full package the platform has to offer nowadays.

A 100K hardware sales boost is miniscule on the grand scheme of things, considering claims that Halo is a huge system seller that's not a big number of systems to move off of the back of a game release.

No, Halo 3 was the huge system seller, the game sold 12 million units, no Halo game after that sold more, which proves the audience wasn't grown because of a single Halo release after Halo 3, rather some of the fans of Halo 3 decided to try the games released after that, but later Halo games didn't create a new audience by themselves, the library effected the sales of the platform, not a single release of the series.

There's no way to know how big Titanfall may become, Halo 1 and 2 (sold 8.49 million according to VG Chartz) didn't move the numbers 3 did, they also had a very well focused single player campaign with a deep lore surrounding that, yet Titanfall has still managed to sell 4.24 million units in like 9 months, not bad for a new IP, even Halo 2 didn't move units that quickly and it had more going for it.

Status of "huge system seller" demands that a single game moves big numbers because it lands on the platform.

All the Halo's after Halo 3 only boosted hardware because Halo 3 existed? That's what I said, not hard to understand really. The biggest selling Halo game on any platform, sold 12M units, no later Halo release sold more, even the week Halo 3 came out there wasn't a huge sales increase on the level of something like Destiny (440K units of hardware vs like 2.2M units of software)

Am I reading this incorrectly or what? Yes you're reading it correctly and it makes logical sense.

Because sales boosted quite a bit the week each of the Halo's released, Not really even though Halo 3 sold 3.8M units of software, it still only caused HW sales to go from 164,012 to 231,539 in the week Halo 3 came out, that's only a 67,527 increase, not that great really, what that tells us is that most people interested in Halo had already bought and XBox 360, the same is likely true of Halo 5.

common sense would dictate that the 360 systems sales rose on those weeks because Halo is a system seller. It seems like your trying to come up with random reasoning for why the system boosted so much in one week when each of the Halo's released but there's a simple answer; Halo is a system seller and that's that.

You're majory failing to prove your point, where's the inarguable proof of halo being a system seller?

In order to be a system the series needs to cause hardware sales to increase proportionately with the software sales when game from that series come out, but that isn't what the numbers tell us, not at all.

Actually the games sell inarguably well, there's no doubting that, but the hardware sales don't rise in line with the software sales.

Halo 3 proves this, by only selling 67.5K 360's the week the game comes out, even though Halo 3 sold 3.8M units of the game.

360 sold 129,865 the week before ODST came out, but the week ODST released 360 sold 147,808, so ODST only caused a rise of 17,943 in XBox 360's hardware numbers.

Then looking at Reach, it sold 3,698,137 in software, but the week before the game came out Xbox 360 had sold 158,605, the week of Reach coming out it sold 264,466.

Then looking at Halo 4, it sold 3,662,557 software, 360 sold 241,278 the week before H4 came out, but 379848, so Halo 4 caused a sales rise of 138,570, dispite the game selling 3.6M units of software.

That tells us that the install base was largely there for Halo on the 360, people had already mainly bought the platform before any of these Halo games came out, with ODST being the weakest system seller and Reach being the biggest system seller, but none are really huge system sellers and that's what the numbers support.

Of course most people already knew Halo was coming out on the system, so they had already bought the platform.

The same will likely be the case for XB1, but we'll see what happens when Halo 5 comes out.

If Halo 5 sells over 3 million the week of it's release, but the hardware only rises by 150K

How do you know only the die hards are the ones that must jump to buying the system because Hale releases on it? How many people do you have compiled into your survey (I'm assuming you have one...not)?

Because that's what history tells us, the game always sells well, no one can dought that, but the hardware sales don't rise in line with those software sales, they're always far lower, well below a 10th of the figure of software sales, I've give you the numbers above, but feel free to double check them yourself.

And how do you know most people think about the full package when games like AC: Unity/Rogue released just last year are among the most knowingly bugged and incomplete game and still went on to sell 10 million units?

Because it's logic, a mulitple 100 dollar or pound device usually warrants thinking about what you're going to want to do with it.

If people only bought a console for one game, then hardware sales would be in line with that one game's sales figures when it comes out, that doesn't happen, in fact there's usually a huge disparity between software (being the highest figure) and hardware when most games come out.

Halo is actually an example of this.

A better reasoning would be the same reasoning why all the other Halo's sold such huge numbers, Multiplayer with friends and a bumping community.

Not really, Halo has huge numbers, because the people who want the game have already bought the console.

Multiplay and friends playing is one thing, but it's not the full reason, but people have already bought the platform because they have known the game was coming, but Halo isn't the only game they want, they play COD, they play Battlefield, Forza, basically everything that interests them.

Halo doesn't sell systems because Viva Pinata or Forza or GTA exist on the console, Halo has always been able to sell on its own, the original Xbox is major proof of this.

Halo has already had it's effect, because the game was announced for the system and people knew it was coming. History shows that people bought an XBox 360 well before any of those Halo games had come out on the system, the fact that even Halo 3 sold 3.8M units of software, yet 360's numbers only rose by 67.5K shows this is the truth.

It looks like you can't handle the truth, but I'm afraid the facts are what they are.

100k is the first week only. People don't just stop buying Halo or Xbox's a week after release. Some people have to wait until their birthday or christmas and on those days Halo will reach out to a huge crowd of people because Halo is one of the biggest single games to drive sales for the Xbox platforms, always has been and will continue to do so. If you think that Halo isn't a huge system seller on its own when their is proof that it is then that's your choice to ignore it.
