1. Final Fantasy VII
This is the only game on this list that I still play, and finish at least once a year - and it's a huge game. When I first played this game, the graphics, the music and the characters really excited me. It was my introduction to the Final Fantasy franchise, so I had no idea what to expect, but after playing so many turn based strategy games for Playstation, and then digging my teeth into this one, it was pretty clear that this game was something special.
A lot of games put me in moods, or I need to be in the right mood to play a game, and Final Fantasy 7 seems to fit so many of my moods. Thinking of the music, and even the menu sounds, makes me happy. There are several different ways to play this game, focusing on different characters and battle tactics. There's an open world to explore, crazy hard monsters to kill, and extremely rare materia to find. I'm rarely put in a bad mood while playing it. It's not a frustrating game, but it's very rewarding as you progress.
I love the world of Midgar, and the planet they created. All the characters you meet along the way offer something unique and exciting to the story line, and I look forward to playing with all them. Cid, the cocky pilot, RedXIII the world saving dog, Vincent the genetically altered, kinda vampire creature out for revenge against Hojo, and then there's Sephiroth, one of the most memorable, crazy storylined villain I've had the pleasure of killing.
It's the best game I've played on PSX, and it's one of the best games I've ever played, period.
