I would highly recommend the original if possible. I feel the remake removed a lot of the atmosphere and direction in the pursuit of showing off asset fidelity. The original holds up amazingly well for its time and feels like playing a painting.
And the absolutely horrid framerate is the thing that I remember most about the game. It absolutely ruined the experience for me and made me stop 'trying' to play it.
And no, it isn't me a primarily a PC gamer complaining about 30fps. It was like 15-20fps. It's was absolute ass, bordering on unplayable.
It's like you weren't grappling with a colossus, instead you're constantly fighting the laggy 15fps framerate.
And I don't mean it just by the standards of today, I mean by standards of the day.
God of War games hit 50-60fps pretty well on PS2 and had all the epic bosses and set pieces
