Hmm. Well, probs the oddball in this fanbase but here goes. This'll be the games I played and mostly finished and on a scale of personal enjoyment.
Resident Evil 1 - 0/10
This is entirely on me. I've never once enjoyed the first entry in any game series. It does not matter what series it is, even my favorite series are not safe from this, I found RE1 boring, dull, and honestly, my biggest threat in the game was staying awake while I attempted to play it for the first time.
Resident Evil 2 - 8/10
Found it enjoyable, I never found myself frustrated or bored, while as per RE standard, voice acting was terrible and despite my personal gripes with the story, it was honestly the closest I come to having enjoyed the classic RE. Although having something chase you isn't my cup of tea and those segments with the tyrants are more groans of dread at being rushed rather than fear.
Resident Evil 3 - 6/10
Suffers a little bit from what I experienced in RE1, left me bored, I didn't exactly have a care for Jill also hurt it quite a bit.
Also from personal memory it felt a little too linear for my liking having to backtrack really long hallways just for a minor object I missed. It was on me, but still wasn't a great first impression.
Resident Evil 4 - 7/10
A pretty fun game, it was rather an enjoyable experience and had the perfect mix of horror and action early on, but just had a large shift in the later portions that felt like it came out of left field and was just slightly frustrating. Also instakills at every corner is still relatively annoying. Same with QTEs.
Mercenaries was great though.
Resident Evil 5 - 9/10
Improved RE4, decided it was going to be campy and ridiculous and ran with it the whole nine yards, I appreciate that. I also appreciate that it wasn't as QTE heavy like it's predecessor or sequel.
Campy as all hell story, super hammy dialogue, some ups and down with the story, but all the other content such as online and mercs covered for that games flaws in the story, it used it's mechanics to the fullest in those modes. I have very fond memories going online and helping others in the campaign. The co-op was fun and relative to the classic RE games I found the VA was cheesy, but actually good. It grabbed everything it had and ran with it.
Resident Evil 6 - 8/10
While I believe the story as both a whole and individually was mostly garbage, the character interactions, voice acting, co-op, made up for where most flaws were concerned. Most locations are rather well made and even balanced, even on the hardest difficulty. (Professional. No Hope was an addition iirc.)
Probs the only game where the movement was on your side and not you having to learn to manipulate it.
Mercenaries also reached the peak in this game.
Resident Evil 7 - 5/10-
Personally, First person games are not my cup of tea so I already was going to enjoy it significantly less than any other game in the series.
It has a good feel starting off, but around mid point, it just does a screeching halt. (I believe quite literally the moment Jack kills himself the entire game just does a major shift imo.)
The second half of the game was not very fun for me, and it felt like a blemish on the first half since just like RE4, it came out of left field.
Extra content modes are also ehhh. So I don't enjoy the game anything past the first playthrough.
Resident Evil: Revelations 2 - 7/10
Fun budget game, feels like a arcade-style game. Also campy, but the story is meh at best. Also have a lot of gripes with the story and character's logic, even among the other games insanity, they just are stupid in this sub series and just oof. Designs are not to my liking either and to be quite frank, the game doesn't exactly use it's mechanics to the fullest like the Raid mode does which is odd to me.
But like literally every action RE game, the extra content make those games very enjoyable when otherwise I wouldn't, so I appreciate it.
The RE series is up and down for me. The classic games were all over the place for me. And I found a few of them to just not be fun for me in the slightest. But hey.
Honestly speaking, I enjoyed the spin off games much more than I did the main series because they tried something weird and it just worked.
But I love the lore, characters, world, and design of the Resident Evil series so I still stick around.
