As I am finishing up Ada Wong's campaign in RE 6 I'm realizing the biggest issue issue with it is the designers ideas about adding variation to the game.
RE 6 bases it's variation on things outside of it's core mechanics (QTEs, vehicles, stealth, swimming, forced running, and really bad puzzles). Except none of that variation is fun because none of it is flesh out. The core mechanics don't support stealth. They either have a direct line of site on you or not and that's all that matters. Camera doesn't support looking around angles well? Too bad. Extravagant kill animations make the stealth make no damn sense? Too bad. Caught by the enemy? Sucks for you, you only got that one chance and you will now be swarmed by every enemy in the level and there are no mechanics which allow you to hide again. And it's not like it's a one off thing! Sherry chapter 2 and 3 and Ada chapter 1 (and apparently chapter 4 from what I've heard) all have stealth sections in them. Same with the vehicles. Why are there random Snowmobiles in Sherry chapter 2? The level isn't big enough for them and you can only drive them in that small section and they control like shit on top of that. Sherry/Jake chapter 1, 2, and 4 have vehicles as does Chris/Piers chapter 3 and 4 do as well and I know Ada will have have one based off of the Leon/Helena campaign. The swimming section in Leon/Helena chapter 3 and Ada chapter 1 wouldn't be so bad if the controls were worth a damn, but they aren't. And then there are just little things like edge slipping in Sherry/Jake chapter 1. Why is that even a thing? Why is grave slipping in Leon/Helena chapter 2 a thing when it then gives you a fixed camera angle that makes it impossible to fucking shoot at anything (it might have been clever if not for the fixed angle shit)? And can I just say: The "Press A to make Ada shoot the rappel gun and watch her do a cool flip" could have lead to a cool gameplay mechanic but nope, just "press A".
And then there is shit that I just can't believe passed the design phase:
Who the fuck thought it was a good idea to make it so that you can barely see (there are points in the level where visibility is even worse) as you have long distance enemies
and enemies that fly around!? Or to make it so that if you are knocked down at the top of the hill, the ice in the level will force you to slide all the way back down to the bottom with no way to stop yourself? Or the previously mentioned issue with the snowmobile? And then adding in a mandatory stealth section after a mandatory vehicle section? And then top that all off with a QTE section?
This is the most fun you can have in RE 6:
The added variation should have exploited those mechanics to their fullest, because as Mercenaries showed, RE 6's combat system is a damn fun time.
And that's why I like Leon/Helena the best: It's lacks the most amount of bullshit.
