Well my favorite game is probably obvious, lol. I love the Final Fantasy series in general, but especially 6-10. They are just amazing and pretty much at the top of my list. I could go on forever, so I will shut up about it to spare you all. Just remember that Final Fantasy 8 is the greatest thing to happen to this planet. I will find you and make you pay if you disagree.

Other games:
Dragon Quest 8- It's just such a fun adventure with great music and story telling.
Castlevania Symphony of the night- I love the Gothic feel, the atmosphere and the music.
Legacy of Kain: Blood Omen and Soul Reaver Series (excluding blood omen 2)- The voice acting is amazing, great character development, and one of my favorite stories in Videogame history. Sadly it was butchered by the second blood omen and never given a proper finale
Silent Hill 2- Everything about it makes it amazing.
Resident Evil Code Veronica. How could no one mention this one? Nemesis is right behind it though.
Parasite Eve one and two. Squaresoft, nuff said.
C
hronos Trigger and Cross. Read the above, lol.
Zelda Ocarina of Time and Majora's mask. Just amazing games, except for the annoying save system.
Elder Scrolls Oblivion. Wasted too much time on this one, but it's great. Haven't played Skyrim yet.
Sadly there are many more games and I've wasted much of my life with this stuff; however, I really stopped gaming for a good portion of my twenties. Looking forward to soon playing the Demon soul series, dragon age series, and skyrim, all of which I own yet haven't even opened. While I wait to hear about my job status and am off for another month, I may as well kill time with gaming and get back into it.
