What changes are you guys hoping for?
Here are my wants:
-RE1/RE2 Mansion-like level design. While I love the linear level design of RE4 since it offers for more variety and specific gameplay encounters, I think a a good way for this remake to stand out and offer a different experience and pacing is to have a map that encourages more exploration, backtracking, opening up shortcuts, and needing better knowledge of the map layout. This type of level design is hard to pull off, but its something early RE games excelled in, and given how well the level design in RE2R was, I have confidence that the team could pull this off.
-QTE without button prompts. If QTE cutscenes were taken out, I'd really miss seeing the cool death animations and scenes. I think the best way to handle this is to do it like the final cutscene in RE3R. In RE3R, there is a part where Nicholai has Carlos hostage with a knife, and you have a moment to shoot Nicholai. If you succeed, you get the ending cutscene. If you fail, you get a unique cutscene with Nicholai killing both Carlos and Jill.
-Melee attacks/finishers. This is a must. I'm not asking for DMC levels of combat options, but this is RE4. There will be more enemies on screen at once, and few things are more satisfying than using your roundhouse kick for crowd control. RE4 lacked finisher moves when you knocked an enemy on the ground, and it leads to some repetitive knifing of fallen enemies. Streamlining it with a finisher move (ala, RE5) would keep the pace up. Either that, or make knife slashes faster. Heck, maybe a stamina meter could be incorporated to keep you from abusing quick finishers.
-Ashley stays more or less the same. People hate Ashley, and I pity them for that. Ashley is hilarious. She's annoying, but that's the point. She's a spoiled brat that you need to protect. What makes this work is that she is constantly the butt of the joke, which makes you stand out among RE characters. It also highlights her contrast with Ada--the ultimate femme fatale. It's also great that she has a crush on Leon, and he just laughs at the thought of "overtime" with her. Making Ashley capable to fend for herself or "badass" completely misses the point of her character.
-An improved Separate Ways. The OG SW was kinda dull. I'd like to see Ada's grapple be more incorporated into the gameplay, making previously explored areas as Leon feel completely fresh. I know its a modern day gaming trop to just add a grapple hook and call it a day, but this was a thing that was in the original Separate Ways that was very undercooked. In addition, if the main Leon campaign is less combat driven, they can really up the combat with Ada--having more arena style map design, more melee options, and more sci-fi type weapons and gadgets leading to a completely new playstyle.
-An ever more robust Mercenaries mode than the original. Mercenaries was taken out of the RE3 remake, and it sucked ass in RE8. This is the time to go all out, especially since RE4 is really the game where Mercenaries became legendary. Adding online co-op as an option is a given, but I'd like to see the roster get an upgrade. The original RE4 Mercs let you play as Leon, Ada, Hunk, Wesker and Krauser--all having completely different playstyles. All these characters must return, and in addition, add Luis. That's a good start, but RE5 even went crazier with its roster of Merc, and I think RE4R should at least try to match that. I'd be totally fine paying for DLC character pack that includes Chris, Claire, Carlos, Jill, etc.
Also, don't worry about balancing the characters. Part of the fun of RE4's Mercs was just how fucking overpowered Krauser's parasite arm was!
-No cutting of bosses or enemies. It's wild how many enemies the RE2 and RE3 remakes cut. I want every enemy type to return in RE4R, and if something doesn't, replace it with something better. Keep in mind that the shark in RE1 was super lame, yet the REmake didn't cut them. In fact, REmake reimagined the shark tank as the most intense part of the entire series! I hope that mentality is carried over for RE4R.
