Parents should beware as loads of blood, guts and frightful sights fill this game. Having said that anyone looking for a good scare should definitely check this game out. In case you missed the news, this is most likely the final version of Resident Evil to appear on the PSX. If you've played through the other two PSX versions then this is a must.
Even the casual fan of the series should own this game because Resident Evil 3: Nemesis is the culmination of the entire series and comes with most of the fixes (mentioned in the review) that gamers have wanted since the original.
