Aw ****, dudes. My favourite always changes! It's like Final Fantasy for me.
Here's a boring-as-**** rundown of what I feel about my top picks. Don't wanna read it all? Tough. Read it. Punk!
RE2:
Most nostalgic for me! The story is a step up from RE1/REmake, and I love how the T-Virus makes its way to the city and the stakes are immediately much higher than RE1. You're thrown into the middle of Raccoon City and you're completely surrounded by enemies with no healing items, so I died a few times trying to get to the R.P.D. on my first attempts. The game did a great job making me feel powerless outside the station, so I felt trapped within the R.P.D. That's great horror. RE2 also introduces Claire Redfield, my favourite RE character.
RE3:
People say RE4 is the one that took the series into the action genre, but I think this one is the one that really started it. Nemesis makes this game for me. I've never felt such pure terror and panic as when I'm fighting or running away from him. Nemesis, unfortunately, has a major downside: he forces the developers to place enough ammo in the game for you to take him on in every encounter. This has the unfortunate side effect of giving the player far too much ammo for the rest of the enemies, especially considering you can evade the Nemesis on all but 3 encounters in the entire game. I've beaten this game without picking up a single Gun Powder and I still had in excess of 30 grenade rounds left; just take a minute to process that.
However, I love how Nemesis is difficult to fight even with powerful weaponry. A lot of horror these days is created by giving the player no weapons, but RE3 gives the player an arsenal to rival Sylvester Stallone and yet you feel just as helpless when the Nemesis rounds the corner.
Unfortunately, what RE2 did to make you fear the hordes of enemies in Raccoon City, RE3 undoes by throwing you into the horde with too much ammo. Another major thing this game has against it, for me, is the absence of Lickers. What in the actual ****, Capcom? WHERE ARE THE LICKERS IN RE3? I do love this game, and probably enjoy it more than the others, but I can't call it the best one.
RE4:
I don't think this is the best game ever made. Sue me! It's a fantastic game for what it is, I've played through several times and always have fun, but I always have to remind myself that it's a Resident Evil game, and I always have to remind myself that I'm supposed to be playing as Leon from RE2, because he is absolutely nothing like his previous character. They really should have made more of an effort to make Leon more recognisable because nothing else about the plot is anything to do with Resident Evil. It all feels really unfamiliar.
Also, this game SERIOUSLY lacks the ability for Leon to strafe. I wouldn't really desire that option if Ganados didn't constantly throw their weapons, which is something you can't really avoid unless you catch them winding up for it and shoot them, or shoot the weapons themselves - something that's far more difficult to do than just STEPPING OUT OF THE GODDAMN WAY. This game is infuriating on a first playthrough because a lot of the game is designed for you to fail first, and to learn where the enemies are positioned so you can sneak in with exactly the right type of weapon. Knowing exactly what's through the next door won't help you when it comes to the damn water room though. I also hate Quick Time Events. The only time it's actually "good" is during boss fights like Krauser, It, and Verdugo, and during the knife-fight cutscene with Krauser. The boulder sections are ****ing stupid!
I said bad things about RE4 - I'm waiting to be crucified.
REmake:
Probably objectively the best one. Absolutely gorgeous, and a perfect remake. Preserves everything good about the original and adds so much more that enhances the experience; Lisa Trevor, Crimson Heads, and the fuel cell section to name a few. Stunning scenery and beautifully orchestrated scares - one of the best survival horror experiences available! I also think the mansion is one of the best examples of level design in a video game, both in this one and the original RE1.
Overall, my favourite is REmake.
