So, people who go into this expecting it to be an FPS with tiny RPG mechanics like fallout 4/76 are likely gonna be SUPER disappointed. Its more like morrowind but with guns, in the sense that you can shoot like an FPS, but its far more an RPG with far more RPG mechanics. I explain it in the paragraph below.
The game isn't going to be an FPS at all. By that, combat is very slow and dragged out and enemies are extremely bullet sponges. There is no going to aim for the head and one shot kill and pew pew everything. And from what I'm hearing, not only is the combat very slow paced (but still actiony, its not actually like morrowind, its just nothing like a FPS where you one/two shot everything), its better to use stealth and strategy (in this way kinda like deus ex from my understanding). I actually like this, cause in a way it goes back to a semi fallout 3/NV playstyle where its more RPG and less FPS run and gun. But there will definitely people that don't like that.
You also don't find enemies around every the corner, and can go hours without combat (if you want, you can still purposely look for fights). This part I'm extremely happy about. Wow do I get annoyed as hell going every 3 steps and getting bombed by enemies and can't have any peace or be left alone. Go afk (most of my time afks are real life emergencies or phone calls and dont even got time to pause and this happens to me lots of times a day) and come back freakin dead cause there is no safety anywhere. Almost every freakin game does this and it always makes me rage so much. Most games aren't as bad as WoW though (thats a whole nother level of dumb) where they stun daze you every 5 seconds (or sometimes chain stun daze you), I quit the game cause of that lol. But maybe (some) people like being bombarded by an annoying amount of enemies everywhere they go and might be disappointed by it.
Either way, cyberpunk 2077 is gonna be a VERY slow paced game. So people going in expecting a fast paced shoot em up are not gonna be having a good time. Hence this post as a semi-warning.
