The Final Fantasy series has always been a favorite of mine. In particular, I absolutely love Final Fantasy VII and Final Fantasy IX. Considering the former is the highest grossing RPG on the PlayStation platform, it's needless to say that it is an awesome game and franchise.
Final Fantasy VII:
I love the darkness and futuristic, urban feel of this game. The storyline is well developed, characterized by themes of love, loss, revenge, confusion, and triumph.
As far as the gameplay is concerned, the ATB system that governs the fights is regarded as one of the best of the franchise or any other RPG. It's fun and adventurous from start to finish.
Final Fantasy IX:
I love a game that helps the player escape reality. This game has a fantastical environment and themes coupled with a wonderful storyline that makes it an unforgettable experience. It has many of the same story elements as Final Fantasy VII, and yet is still so very distinct.
The storyline is enthralling and the gameplay and battle system (like its predecessor) are brilliant and seamless. Furthermore, compared to the previous games in the series, Square-Enix (then Square) accomplished huge improvements in graphics, especially with the cut scenes. All this was combined to birth a wonderful, captivating gaming experience.
Tekken:
My absolute favorite fighting franchise is and always has been Tekken. I love the vast array of characters and the fighting styles they bring to life in the gameplay: Karate, Capoeira, Tae Kwon Do, Aikido, Kickboxing, and endless others. My favorite character is Marshall Law, who reminds me (and countless others) of the late, great Bruce Lee. A very close second is Eddy who brings the real Afro-Caribbean style of Capoeira to life.
