I played both FF X and FF X-2 as a kid and replaying them brought back so much nostalgia and fun. FF X is definitely the tougher game of the two; the last stretch of bosses are challenging and require grinding. FF X, IMO, also has the better story of the two but both are good in their own way. I had the pleasure of playing them back to back and it was great to see the full story while remembering all the details. I enjoyed both games immensely. They have that old FF storytelling, world building and charm that has been lost in the new FF games. I will go as far as saying they were a masterpiece of their time and just great JRPGs in general.

10/10

This steam version does have crashing issues. I recommend searching for the below guide on the community hub. It resolved all my issues and I only had one crash in both games which is great.

Square Enix can't be bothered to fix the issue with cutscenes, and the game crashes from time to time.
