Guiltyofbeingtrite said:Parasite Eve series I guess counts, It's got monsters, but attempts to use modern science to explain it their appearance.
edit: action/rpg probably is more accurate.
Despite the odd story I really really liked PE1. I felt it did one of the best jobs of mixing turn based final fantasy style RPG elements with action shooter elements. The weapon customization was fun, the monsters were creepy/fun and having a strong female lead (as opposed to what they did with The Third Birthday) was awesome.
It had shortcomings sure, but I'd still hold it up as one of the best games on the PS1. I liked it alot more than PE2.
