Crafting was in most of the games in some capacity - combining herbs and other items, etc. RE3 was the first game to have crafting ammo, and they brought that back in 7, the 2/3 remakes, and then 8.
I vaguely recall talking to you over a year ago about wanting to play through all the RE games sequentially because it had been a while since I played all the ones available on gamecube and there were several more recent ones I hadn't played yet, and it took about a year to do it because of adulthood etc. I subbed in the RE2 and RE3 remakes for the originals, and I missed Code Veronica X because I played through everything on steam and for some reason that's the only main game not available there.
The remake of RE1 is still my favorite. RE4 was a landmark game for a number of reasons, but I think it departed too much from the feeling of RE such that it may be a perfect game, but it isn't a perfect RE game if that makes any sense. Then 5 and 6 learned the wrong lessons from 4 and departed even further into pure action and the plot/characters shifted further into like superhero anime, hence the need for a reset (the two Revelations games I think tried to find balance, but they were also comparatively forgettable and the characters were very anime).
But those earlier hours of 7 successfully triggered all the long-dormant horror anxieties that I hadn't experienced since I played 1 as a teen so it definitely gets accolades for nailing the authentic feeling of what RE is supposed to be (also the FPS perspective and playing with a headset both totally amplified that by factors). And then RE8 felt like an attempt to marry the spirit of 1/7 with the spirit of 4. It doesn't rise to the top in either one of those categories, but it felt like a near-perfect cocktail of both sides.
A 2/3-style remake is in development for 4, so we'll see how that shakes out. I recall Capcom reset development because the team was adhering too close to a literal remake instead of a more spiritual remake like its two predecessors, so we'll see. I also didn't think there was a need at first, but playing the 2/3 remakes really made me realize that the "modern" remake of 1 is nearly 20 year old and it might by time for a re-remake.
