You know, the funny thing is that I remember a lot of people asking for something like this in the years after the OG RE2. Like how awesome Mr.X was and how sad it is that he doesn't appear more often. Now Capcom actually puts him in more permanent in the Remake and again people complain. I'm a bit puzzled... I mean, yes, he can be annoying sometimes but before and after his appearance you have the chance to check out the police station without him hassling you, so I don't really see what everyone is complaining about... He does exactly what he actually always was supposed to do.
I kinda expected Nemesis to be just like this in the RE3 Remake and was a bit disapointed when all his appearences ended up being scripted. Pretty sure this only happened due to the complaints about Mr.X.... You guys really don't know what you want....
I think it's difficult to find a good balance. I personally don't like the idea of a invincible stalker. I ended up liking it in OG RE2 because Mr.X was intimidating and his encounters scripted (and not so much).
Now it's too stressful for me.
From what you say about REmake 3, I might enjoy more Nemesis in it than in the OG.
Mr X has always been divisive, but I think Hardcore has taken away any enjoyment you might have had. Normally it's a game of cat and mouse, and you can lose him but if you fire bullets he will eventually be drawn to you. The fade in of the music and footsteps heard in the distance create tension, and sometimes you get the opportunity to hide out of sight so that X leaves the room. He can also be downed, giving you time to take care of business/run.
Truth be told, I think a restart might be worth it. If I get a bit of time I can throw together a a quick guide with puzzle solutions for things you've done so that if you want you can catch up as quickly as possible.
To be honest, Mr.X himself never really killed me. Just the fact that he's following me is annoying. Hearing his footsteps is just making me eyeroll and "Him again !" because it means I have to hurry and potentially run into my death because I don't pay attention. I think if he starts showing up while I have to solve some puzzles, he will really piss me off. I am not a really huge fan of the small cat and mouse game where I have to turn back to take another way around. EDIT : I really don't like to be force to runaway. I like to take my time to analyze a situation. I had to run through the whole underground because dogs, zombies, no ammo and I really didn't like this kind of situation.
I'll see for the restart. Now that I have cooled down, I realize my situation is not so bad. I have like 2 mixes of herbs, 1 spare ink ribbon, access to the magnum ("Lighting Hawk" I think) with quite some ammo for it (and it looks very efficient as I tested it and it one headshot was enough to kill a zombie), no so much ammo for Mathilda and shotguns but I have few gunpowders in stock or to grab here and there.
I am somehow really stubborn in gaming and I can try again and again some situations for quite some time (I am the guy who spend 2 hours on the Tree, sentinel at the beginning of Elden Ring, to defeat him fully knowing I should come back later. Also 20h row, in several session, for Malenia refusing to adjust my build because... stubborness).
So I guess I'll try a bit more and see how goes my next session (get the part of the jack, library trip, clock tower I guess then back to the underground to put back the electricity) before deciding for a restart.
Don't want spoilers but I have to ask how far I am from Leon's ending ? Do we visit the lab like in the OG ? I have the hope once I get the card in the prison cell of the journalist, I can escape from the parking but that would be too easy I guess xD
