This is from that other RE thread that got smushed:
I got it. Wow, this rocks! I'm at the Castle.
They definitely transitioned to full 3d very well. The game still looks beautiful. An added benefit is how it's easier to move around when the camera is always behind your shoulder (instead of different positions depending on whatever still/prerendered scene is loaded as in past games). Sounds is great too on my headphones, I wish I hard the hardware to support Dolby Pro Logic II surround.
There's lots more ammo, but lots more to fight. These new baddies are ever so much more interesting than zombies. They throw axes at you (which you can shoot if you're quick!), weild various weapons that you can shoot away, can do dodge manuevers and move quickly at times, get over obstacles to reach you, etc.
I once climbed a ladder to get on a rooftop, then saw that I could kick the ladder down so that the baddies who were after me couldn't reach me. But to my surprise I saw that ladder reaching back up to the roof, they had righted it and began climbing up! Also fun to shoot sticks of dynamite in one baddies hand when he has several buddies around him (not easy though). A lot is possible with how you can aim more precisely now (also thanks to full 3d).
The whole currency/buying/selling is very nice too. I bought increased inventory space and some pistol upgrades so far, sold some treasure I found.
If you have a Gamecube, get this game! Even if past Resident Evils weren't so great to you, this may be different.
EDIT:
Not really a gamecube fan but I think this is the best game out of all the games I've played on the 3 consoles (xbox, gamecube, ps2). Best graphics, best sound, best gameplay, just a great game.
This isn't the only awesome/exclusive GC game. The two Metroid Prime games are top quality, Zelda: Wind Waker is great, Super Smash Bros Melee for multiplayer, the other Resident Evils on GC are pretty nice (not as good as 4 though), F-Zero GX or Mario Kart for racing, another Zelda is coming up that goes the realistic graphics route, etc. The system is like $100 now anyhow.
Imagine if this had been a launch title... ah what that would have done for the 'Cube before the kiddie reputation set in (if not before it even launched though).
