Well the closest competitor to GT is also a first party game and it is up to its eyeballs in multiple season passes, deluxe/ultimate editions and in-game monetization.
Assuming we're talking about Forza here, you could also argue that it launched with more content than GTS has currently, whilst historically having nowhere near the initial sales. It has more frequent releases somewhat balancing that out, however a single GT will outsell the Forza releases over the same time period, and Turn 10 contracts a large number of people. Basically, there's again a whole bunch of variables at play making one case not really applicable to the other. Forza could well be a money-losing IP without post-launch revenue.
This is true, but assured IP gives you even bigger incentive to nickel n dime your install base.
Sure, but that's not relevant to the point on whether or not free post-launch development is feasible.
Yeah but that has never stopped publishers from selling you remaining pieces for a price. PD not doing that is definitely not because they're apologizing for lesser content.
It depends really. GTS is very much a case where there was significant criticisms of the game lacking content that was expected to be there in the base product, and much of the added content reflects that of which was previously expected. This actually is a rather common theme across many of the games that see free conten post-launch. Sea of Thieves saw complaints that it was lacking content, and so much of what is being added is at no extra cost. Splatoon saw complaints of being lacking in content, and similarly saw additional content added for free, bringing it more in-line with what people expected it to have at launch.
Even in cases where a game is charging for
other post-launch content, there are often free additions made where base-content is deemed lacking. Forza Motorsport 5 adding Nurburgring, Street Fighter V adding more singleplayer content for free, Halo 5's added game modes and maps, Driveclub's weather and tracks, etc. Whilst it does sound negative, "apologising for lesser content" is pretty much what many of these titles are effectively doing, and is why announcements of such updates very frequently (and was also the case with GTS) cite hearing "player feedaback" in regards to content.
That's on Ubisoft though. 'We used more people to do this job than other company so we should get paid more' is never a good excuse.
Well, if that's what's required to create the product, then it is what it is. It's actually an excuse that we largely do accept as standard, but more often when the difference is more readily visible to us (indies and remasters for example).
If GTS had launched with all the content that it'll see added for free post-launch, and then charged for extra in the coming months, would you have considered it to have been a worse valued product as a result? Because that feels like logical conclusion to the argument you're making... that no matter how many resources you expend to make the original game, it would have been preferable to have just offered some of that post-launch instead.
