I may be biased towards this game in comparison to other resident evil games as this was the first one I played. If you already have it on the gamecube, the wii controls are great - however, sometimes I feel that the wii mote makes it slightly easier than it would be otherwise as you can very quickly and accurately move across the screen getting headshots if you have a steadyhand. Also the auto knife (just shake the remote) sometimes keeps slicing down at the ground 2-3 times more than you wanted which can cause a slight ammount of trouble when under pressure. So I wouldn't suggest buying this game again if you have the cube version. Seems like the it would be same game only a bit easier. However, if you do not own the Gamecube version. I would pick it up if I were you, I debated it for a long time as I'd never played a resident evil game - but it was very worthwhile. It really isn't that scary. But that didn't bother me as I'm a wuss with fear anyway. The location damage is very accurate as well. Ie shooting in the shins will drop a zombie to the floor where as the thigh they just kneel down. It took me 13 hours to beat on normal and I have just started professional mode. The extra missions from assignment Ada and Separate ways, although fun, don't make too much sense with the rest of the game sometimes not to ruin a surprise, but you kill someone in the main story and in Seperate ways which is designed to be going on side by side with the Main plot
Some boss fights were a bit too easy however, such as salazar I managed to kill him standing in the same place without taking any damage. Other bosses were a real challenge, krauser for instance is tricky as you have a time limit as well in which to fight him.
After you have beaten it you unlock mercenaries which is in my opinion, one of the better parts of the game. You have unlock new characters, it isn't too hard, but its hard enough to not be a walk in the park. However, once you unlock Krauser in mercenaries it gets abit easy again as his bow is powerful and although its cool to blow up heads constantly with a bow, the game starts to feel a bit dull killing almost everything in one hit...
The game does have replay value however as professional mode is very different game because of the monsters you have to fight, you get different events which are designed to challenge you much more, I wouldn't suggest playing on easy even if you don't think you're any good because you miss out a lot of the events such as chainsaw zombies around the corner.
Overall I found the game to be a great experience. Not sure how it would compare to other resident evil games due to the different aiming system, so it may feel very different but not all different things are bad right?
As a small note to parents thinking of buying for a child, this game really should be an 18 in my opinion, I don't understand why it isn't as at the start it gives you a warning, everytime, about strong language, violence and gore. Also large blood splatters in some places make me question how it was only an 15.
I would (and have) recommand this to a friend.
