fantastic game and well good experience for anyone who plays it
The cinematic presentation of the game is just overwhelming. It's almost like a movie is playing before your eyes sometimes, and though I've played it through several times, I still find all the scenes immensely satisfying. The action-responses that made the scenes even more interesting (and necessary) to watch are perhaps even more enjoyable this time around due to the Wii's motion controls. Sprinting, swimming, cutting, knife fighting (personal fave), and more are done by moving the wiimote in some way. There are still some of the A+B ones though, to balance things out a bit (or to do something where moving the Wiimote wouldn't make sense).
I never played Mercenaries in the old GC version of the game, but boy did I miss out. It's RE4 action at it's finest, and the WIi controls make it more enjoyable than it ever could have been in previous versions. It offers an insane level of replay value, partially due to it's immense level of challenge and intensity.
Separate Ways, Ada's own set of side-missions, explain many little details to fill in the plot (and add to it), and are enjoyable, even if they aren't as interesting as Leon's epic adventure.
The main game is intact and as enjoyable as ever, as the Wii controls add to the thrilling and strategic fights. The very satisfying cinematics are all here, and the game overall looks better than ever (even though no significant graphical advancements were made from the GC version).
If you never played RE4 before, buy this game now. Even if you have, you'll love what the Wii controls add to the game and should at least give it a try. I found myself buying the game right after I tried it out, simply because the Wii controls are so great; that, and I never got to taste the additional content released on the PS2's version of the game.
This is easily the definitive version of RE4, and still the modern classic it was a few years ago.
