I loved Deus Ex: HR, it was one of the most atmospheric and engaging games I've ever played (since the original Deus Ex at least.) I much preferred it to Mankind Divided which, while I enjoyed it, departed too much from the atmosphere and sort of noir vibe of HR imo.

That said, as I said in another recent topic, and will quote here, while the comparisons are understandable, I think likening it to Deus Ex misses the point and sells short the ambition of 2077 by a lot.

As I said there:

I think comparisons to Deus Ex are more to do with the modular nature of character builds and the hybrid genre bending nature of the game than anything else. That said, I feel like comparisons to both Deus Ex and GTA V (and Watch Dogs, and Red Dead alike,) kind of miss the point of what CDPR are going for here. I've noticed a lot of dissonance between what I think a thorough digestion of all the material shown so far indicates the game will actually be, and what various groups of players seem to be taking from that material instead.

What Deus Ex comparison inclined players see: Deux Ex Human Revolution but in an open world with driving. This isn't representative of what we should expect, because... Deus Ex - even if we ignore its hub based, mission-based, and static time of day based nature - is much more of a spy thriller narratively and conceptually than Cyberpunk. They do share in common choices affecting outcomes and in-mission options, so there's that comparison to be made at least. But the structure in how it achieves that differs, as do the tone, concept, and intangible "feel," which is of course subjective.

...

What - imo - people should actually be seeing when they look at the material released so far: A moderately sized (by today's massive world standards, and in comparison to Witcher 3) open world that is densely populated, highly vertical, methodically explorable, with its own rich lore, tone, and atmosphere. An up close, low camera, first person perspective intended to depict the sort of immersive verisimilitude and almost simulation-like quality that you almost have to go back to a game like Shenmue to see (not saying they are anything alike - please don't infer that from the reference; speaking solely of the goal of immersive verisimilitude and detail density for its time.)

Attribute and skill based character progression systems that CRPG and ARPG fans should find more familiar than GTA or RDR fans would. Witcher 3 quality storytelling and character-driven narrative, but featuring much more player choice and agency this time around, as we aren't paying a pre-made character (which also sets it apart from the other games mentioned, incidentally.) Featuring a blend of first person shooting, hacking, stealth, and melee, and soft cover, as well as perks and enhancements, implemented in its own way, via systems heavily inspired by the PnP game from which 2077 takes its inspiration.

In short... this is a very different beast. This, if they nail it, is going to be a very special game. The pacing, tone, everything is going to be, while perhaps analogous to past games in parts, cumulatively unlike anything we've experienced before. That's why many people who understand this are so hyped for it. This is something many of us have only dreamed of. A game set in this sort of heightened, tech-noir-like future, in an open world, yet not an open world that prizes scale over density or immersion as so many do. A world all about sense of place and immersive reality. A game which while full of exciting battles (for those who want them - remember that we can do no kill and stealth runs as well,) is also ultimately a slow burning, atmosphere-oozing, RPG experience intended to be taken in and savored.

It's the full on RPG nature of the game, combined with it being truly open world, that is going to make it unique for a game in this setting, and I think people underestimate how important and impressive that truly is.
