How many games right now legitimately can't be done on Xbox One?
Don't worry, I'm confident that there are more games on the way with instant-switching of dimensions...
Next gen games were supposed to take advantage of these new ssd’s to create more seamless worlds then ever before. The ps5’s big holiday game will be cross gen with loading crawl spaces. Xbox doesnt even have a big game this year let alone a holiday game. Im just bummed out at the state of things now
Further ideas about how to use the rapid speed of SSDs to provide entirely new types of gameplay are still to be sought out. You can certainly make games look and play better with an SSD, and they're already doing that to some degree; making a game that could never exist before the machines we have now, that's a harder proposition, and unfortunately, we've yet to see a delivery or even reveal of much of that innovation yet.
As far as cross-gen loading crawl spaces, SSD will help (and already has,) but so will features like World Partition and other new ways of sorting world/asset loading. (It might even help past-gen as well as current-gen, though the benefit you'd get without a SSD is still a question.)
Yes, developers have talked about how these new consoles will help unshackle designers from crutches needed in the past, but it's not just tech forcing these circumstances, it's also just a natural aspect of how game makers are used to making games. Putting a slow section into a game helps technically (you can load the next chunk of architecture, you can reset enemies, you can clear out some data which won't carry on, you can ensure your save data will track properly,) but it's also a function of game design and pacing. Creating a game with zero interruptions, that's a new design paradigm which is probably comparable in some ways with the challenge of going from 2D to 3D or going from levels to open-world, and although it's frustrating, it makes sense that nobody has reached that mile-marker yet.
You know PC has exclusives don't you?
PC does have exclusives, though not many "only possible with the power of PC!" games as it used to. The budgets are hard to sustain at AAA levels with just a PC release. There are some (particularly in strategy and simulation markets, where there are diehards who buy a lot of product,) but it would probably be hard to make a list of first-in-class titles this gen (or past-gen) which can only be played on PC.
So for the sake of conversation about why so few next-gen exclusives are on PC, I would have to say that PC is not currently leading the next-gen vanguard. It's on the high-end of the slider, but it doesn't yet rip the knob off. PC does however have a few games and projects that are really interesting to play and/or take a look at for a glimpse of the future today.
