This was one of my favourite games (if only because I really wanted to finish it) for the PlayStation. I had to play it four times (in a certain sense).
When I borrowed a PlayStation, I played Parasite Eve. Then I played EX mode, but couldn't make it all the way through the Chrysler Building. (For those of you who don't know, the Chrysler Building in this game has 77 floors, with most of those floors being randomized. You can only save after beating a boss on each 10th floor and getting an Elevator Key to be able to leave the building.) As it takes an hour to go through each ten floors, you can imagine my frustration when I couldn't repeatedly got defeated by the cockroaches on floor 50 or 60 or whatever.
When we got bleem! (the first commercial PSX emulator, and also the first we got running on our computer), I gave it another shot, but of course had to play through Parasite Eve another two times (well, one and four/fifths) to be able to access the Chrysler Building again, since I didn't know anyone with a DexDrive to be able to transfer my PSX saves to the PC.
I didn't realize that after Level 35 or 36 or somewhere around there, the EXP required for the next Level drops so significantly, it's easy to get to Level 99 from there. So with a maxed-out Aya and the AK-47 I could finally take down the cockroaches and the remaining bosses.
I must say I was a little bit disappointed at the FMV-less "better" ending, mostly because of all the trouble it takes to get through the Chrysler Building. But I do like the game, and it's probably the first horror game I really wanted to play.
Despite that, I haven't gotten far in Parasite Eve II, which is on the short list of games I ought to finish but haven't.
I look forward to these maps of the original game, if only for the memories.
mephea, are you going to map the non-randomized floors of the Chrysler Building? (I think those are the 1st, 10th, 20th, 30th, 40th, 50th, 60th, and 70th-77th.)
