I've never played a game in the Resident Evil series before as I was put off by the 3rd person style shooting, but one of my friends told me this game was in a similar style to House of The Dead and those kind of arcade games, so I decided to give it a try, and I was quite impressed.
The graphics are on the whole fairly good. At some points things can look a bit 'straight-edged', but that didn't bother me personally as it's the gameplay I was more interested in.
In a word, brilliant. I played this game without the use of the Wii Zapper (just using a free Wiimote and Nunchuck) and found it to work very well. It's hard to go wrong with the first person light gun style games, but this game improves upon the arcade format by including hidden files and character profiles which gives a lot of replay value. There's also the level up system which I thought was a nice touch. It allows you (when you have eanred enough stars to do so) to level up weapons making them more powerful, or increasing the clip size etc.
Not playing a Res game previously, I found this to be a good overview of the series (I'm sure a hardcore Res fan would disagree), but in the end I found it to be a little short and lacking depth. There are quite a few weapons to choose from, but some more vareity would have been better, and you can only level up each weapon 4 times (5 if you count the bonus at the end, but I won't spoil that...), which limits the weapon so to speak (I was constantly running out of ammo despite maxing the weapon out). There are bonus missions included, but overall I think some more levels would have been a nice addition.
Generally, for what it is (not for what it isn't - another installment in the Res series) it's hard to fault this game as it stacks up extremely well against games of its genre such as House of The Dead. If you're a fan of light gun style arcade games (The previously mentioned House of The Dead, Time Crisis, Crisis Zone etc etc etc) then you won't be dissapointed with this game at all.
