Even though, as you would expect, some gameplay aspects don't pass flawlessly the test of time (most of those being the ones that involve gimmicking around with the game's movement), FF7 has an absolutely timeless story, with iconic, charismatic characters, and a jawdropping amount of content that will keep you hooked for hours to no end.
The combat system also deserves a high praise: Materias grant the player an infinite way of playing around with each character's builds, and the variety they have is stunning. They can even make the game's difficulty a complete joke if you know what you're doing, but hey, I had so much damn fun.
An absolute must-play in the series. Excited to play the remakes.
