Gimme a break. They didn't try. Half of those you listed are remasters, and while that is cool and all, I'm talking about bringing new ideas to the table, reinventing the franchises and capitalize off that. Deus Ex didn't even get off the ground before it got cancelled. That's not trying.
And the other 2/3s (and more that I didn't list) were not remasters. That was one of the THQ approaches: remaster the popular original games, get a start-up studio started on the brand, then make original sequels (and in the case of Darkstalkers and maybe others I can't remember, also spin-offs) after the brand is re-established and the team is up to speed.
As far as bringing new ideas to the table... you're typing that, but I don't see that being what you're saying across various posts. You're asking for sequels and reinstated franchises, products which as you said "capitalize on the good will and nostalgia of said IPs." You're saying you want more of what you liked before (and in the case of Saints Row, you want none of whatever new "fucked around and found out" ideas you personally didn't agree with, just plain Saints Row and more of it, please.) We know nothing about this Deus Ex project other than that it got canceled, so try not to jump to the hyped conclusion that it would have been "bringing new ideas to the table" and "reinventing the franchises" since we have no idea if this studio, in this day and age, on an Embracer budget, while at the same time
supposedly contracting staff out to Microsoft to help on Fable, no idea if they were capable of.
THQ and old brands from the '000s and '010s (or older) aren't where I'd expect "new ideas" and "reinvention" to flower. It happens, and it's great when it does, but it's not really what this thread is about. This is about the four-game (and multi-spinoff) Deus Ex franchise not getting a long-awaited and much-anticipated Part 5.
Which brings me to my first response about consolidation. It fucks up the industry and we can see it here in full swing. The bubble has burst and now it's just full survival mode for many of these developers getting shit canned by greedy corporations.
Eh, it can... but I guess we'll never know what the unconsolidated market would have been if the consolidation bubble hadn't been so virulent. Many of these studios suffered severe financial strain or actually closed for a time before Embracer bought them up (some sold because Embracer was working well at the time and they got a good deal to rise along with them, but many of the names on the Embracer roster were rescued.)
I have some concern and level of disdain for industry consolidation being so rampant in that era (too many people were celebrating mondo mergers by saying they'd get Activision games free on Game Pass now or there would be more characters to cross over in Multiversus, and that was a very dark bright-side view IMO, especially in hindsight now...), but it's always been the way of the market for companies to come together and then sluff off fat and then new companies start up from either a dislike of the conglomeration or having been sluffed off or just an independent spirit, and the cycle continues. Some good things have come from companies getting very big and being able to finance huge endeavors. And the indie life or singular publisher-driven business hasn't been without horror stories.
...If Embracer had blithely continued on its path as it had since 2013 and just put out more and more of the stuff they've been doing (including original IP, remasters, and sequel revivals,) I'm not sure what bad could have been said about its consolidation approach? Games were being made, studios were keeping people employed, and Embracer kept embracing brands and brand-makers that were out in the cold.
Everything was more or less fine, until it wasn't.
