The Final Fantasy series is one of the most beloved Japanese RPG franchises. There are so many Final Fantasy games available on Steam, and each one is its own standalone adventure with unique characters, stories, and gameplay systems, so it’s impossible to pick just one game to represent the entire franchise. Luckily, many of the Final Fantasy games on Steam are playable on older hardware. The early games (Final Fantasy I-VI) will likely play best, but FFVII, FFVIII, and FFIX aren’t that taxing, either. Everything from Final Fantasy X onwards, however, will likely be unplayable on weaker PCs and laptops.
As for specific recommendations, Final Fantasy 6 is commonly thought of as the “best” in the series, and the upcoming Pixel Remaster version will likely be the easiest to jump into (the Android version is also available on Steam, but it’s ugly). Final Fantasy 7 is probably the most popular thanks to its unique sci-fi setting, iconic music, and for being the first 3D game in the series. Personally, Final Fantasy 5 is my favorite of the early-era games thanks to its deep and customizable job system. Whichever game(s) you decide to play, each one includes helpful optional settings like speeding up or turning off random battles, enabling invincibility, and more.
