It's like them in that...uh...damn, have I forgotten? Have I mixed things up in my head? Well, here's what I think I remember...
No overworld map.
Zombie-esk creatures.
The battle system is, while random battles occur, they take place on fields that you can move around in, which changes accuracy of weapons and the like depending on where you are in conjunction to the enemies, but, of course, these fields of battle are limited.
You get to mess around with guns.
You're a cop chick, not quite S.T.A.R.S. or anything, just a regular New York city police officer...who's hot.
Just the basic feeling of the game, it's almost always night and the atmospheric music...I'm sure someone else could explain it better...
Now, I THINK there was herb combinations like RE, but I totally think I'm messing up memories w/that one...I don't remember how to heal anymore in PE...
DAMN MY GAME-TRADING IN BASTARD SYSTEM!!!
Either way, it's worth checking out...if you know someone who's got it, or if you can find a place that rents PSX games or something, do it that way first, because, well, that's always best...But you'll probably like it...Parasite Eve 2 is a different story from what I've heard though...But maybe you'd like that if you jump into the series with it...who knows?
