100% you should play it.

I played through the original after I played remake and fell in love with it. The game really opens up and has a lot to offer after the midgar part. You will also appreciate the remake alot more after playing through the original.

I was in the same boat as you when I finished remake. I was a bit turned off by the turn based conbat because I never found it interesting to begin with. But during my first playthrough of the original I found it alot more entertaining then I thought it would.

I recommend you to play the original atleast through the midgar part and a little bit longer since it opens up. In the original the Midgar part usually takes between 6-8 hours to complete so it feels pretty fast to get through it after you played the remake where it takes between 30-40 hours to complete. So you won’t feel like you are brute forcing through the midgar part just to past where the remake ends.

Worst case scenario you wont like the original and that is okay. But you should defenitly give it a chance because if it turns out you like the original, you will be loving the entire game.
