I'm a pretty big Resident Evil fan, so when I heard about the Resident Evil remake for the GameCube, I was pretty excited. Bought that, loved it and sat patiently waiting for RE2.
That's when things took a (slight) turn for the worst. RE2 is a direct port from the PlayStation original, but this isn't necessarily a bad thing. The game itself is excellent as games go, but trouble arises because you may already have this game on another console. If you do, then there's nothing new for you; only die hard fans and those wishing to complete their collection need buy it.
On the other hand, if you're new to the Resident Evil series (Hi, welcome back from Mars) or have just recently discovered it, then it will prove a worthy purchase. The game is well able to hold it's own alongside most GameCube games (it's a timeless classic) and it provides a great challenge. Because it's ported from a 32-bit console, you would be forgive for assuming the worst regarding graphics, but this game is actually graphically more impressive than some GameCube games! Soundwise, the game is pretty good; it helps crate and maintain the creepy atmosphere. The controls are chunky, just the way Resident Evil should be and the plot is engrossing and interesting.
Overall, it's well worth a look for people new to the series, but I'd be hesitant buying it if you already own another version.
