If you pretend they aren't remakes, they're good games on their own. RE3 though feels awfully budgeted. I guess their aim was to get that one out as soon as they could after RE2 was a success. OK, I know the work on that game began way sooner than people believe, but compared to RE2, it's trash in comparison.
I'm not really that fussy about RE2 either. If it never existed at all, it wouldn't upset me. But I did like some parts where they got the creepy aspects near enough right. The police station had that (rarely seen in modern horror games) claustrophobic feeling to it, but the story went by too quickly, to where it felt so rushed. I'm still more engrossed in The Evil Within games, however.
One thing I'm sure you can agree on that sucked with RE2, was the post police station areas. Once you're past the gun store, it's onto the crappy alligator "boss battle" and then you ride a tram down to the lab. That's more or less it. The experience didn't feel fantastic whatsoever. You just get inside the cable car, ride it down, and you're pretty much already there at the lab. What the hell? In the original, you had William Birkin on your ass and the music as you reached the control room was appropriately eerie sounding, like you knew you were nearing your final destination. Here? You had none of that feeling. It was all just one big messed up opportunity.
Even with RE4, I can see them changing some stuff to give some villains depth, but mostly, I think Capcom will be watering it down for time restraints.
