Parasite Eve had as much blood in it as FFXI which is to say, not much as all besides some red mist. It does have some gore (laughable with today's standards). The gameplay was what made it good, a mix of RPG with Resident Evil without the gore (most of the cannon fodder are animal/insects instead of people, typical SE game).
PE2 threw out the RPG element and made it a RE clone which made the game shit. No idea on 3rd Birthday.
