The original FF7 for the PS1 is one of my favorite games. Since the plot is mostly consistent with the original, I can’t give less than 4 stars. However, there is a lot I did not enjoy about this game. The fact that most of the side content is optional prevented me from ranking it lower.
The mini games are fun but there are so many that it becomes very tedious trying to complete them all. In general, there is too much side content to this game. It becomes repetitive trying to complete the world Intel which is mostly the same in each region. Once you finally think you have completed a mini game, a hard mode appears requiring you to complete the mini game all over again. Most of the side content is optional, but it is a massive part of the game to skip.
The battle system is good but not great. It can be very difficult, especially the optional challenges. It requires a decent mix of skill and character/Materia setup, not much strategy required.
Overall, if you decide to try and finish all the side content i would rank the game 3/5 due to how tedious and frustrating it can be to complete everything. However, if you are willing to skip things the plot and core gameplay are still enjoyable.
