I've played 'em all.
I've been with the Resident Evil series since the first game. Before the first game really, as I signed a waiting list to rent the game from my local rental place, and in return, got a cheap RE comic book a few weeks before release. I've been a Day One purchaser of every real entry in the series since.
The Remake on the GC (and Wii, now), is, in my opinion, the best of the series by quite a lot, one of the best survival horror games ever made, and for my money, one of the best games of that generation. Simply put, it embodied everything RE is and should be about. FEAR, tension, atmosphere. Going from room to room with dwindling ammo, hoping to find another magazine and first aid spray, wondering if you had enough ammo to make it past your next encounter. Hearing a noise off camera, and bringing up your gun for 30 solid seconds and waiting to see WTF it was. All gone now.
Yeah, yeah the controls...blah blah...but with the GC's analog movement stick, it vastly helped, and most importantly, the game design didn't lead to any "cheap" kills (i.e. too many enemies on screen for the control scheme to be able to respond to fairly).
That, and the additions were truly excellent:
--Stunning graphics
--Stunning sound and music
--MANY new, large, well thought out areas
--VASTLY improved voice acting
--Better control
--Better item/weapon placement
--Better atmosphere
--Lisa Trevor (aka Stitched Woman Monster) was an EXCELLENT addition
With respect to fans of the RE4, those aren't RE games. They're barely survival horror. They're action games. RE4 was a pretty good action game whereas RE 5...well...mediocre at best, but they were weak as a survival horror game. The SILLY, overwrought plotline, stupid characters and goofy dialogue, TOTALLY ruined the scare and immersion. At least in the first game, the terrible voice acting was a symptom of incompetent translation. In RE4 and 5, it's just goofy bad storytelling, and silly "anime-esque" plot and character influences. That's fine for other genres, but when you're trying to create a "scary" atmosphere, having a ninja fight with "Matrix" Wesker is just stupid beyond belief.
It's sort of the difference between watching a really good, classic X-Files episode from the mid 90's, vs. an anime aimed at teenagers.
As far as the RE Remake is concerned, it's a gem of a game that everyone with the slightest interest in survival horror should play. Like Silent Hill 2, sadly, there will likely NEVER be another official entry in the series anything like it. We've now switched to mindless 3rd person action, CoD shoot outs, and lost anything approaching tension, atmosphere, or fear.
I can think of very few games I would personally be more excited for than if Capcom were to do a competent Resident Evil 2 remake in the same vein: redone graphics, same core gameplay and story, but added new areas, monsters, and twists.
