What is the game that changed your life? why?

Saga Frontier 2 D: The Gustave XIII Arc story make me believe in myself, ignore the things i lack and learn to see how far i can reach using my own abilities and skills D:

GTA SA - Now I know that I must always follow the train.

Modern Warfare 2. Even though it didn't "change my life" in any way, I spent a ton of time playing it. I still do.

Pokemon FireRed. It was the game that got me into gaming.

Doom probably.

The 'Myst' game series. The best fantasy puzzle games of all time.
It's too bad it ended, but all good things come to an end. The novels are a must read to learn more about Atrus and before the first game.
I'll play them through, back to back, and then not play them for 2-3 years, trying to forget all the clues, then play them again.

Assassin's Creed Brotherhood

Call of duty 2. it has learned me allot about the second world war, more than school would ever do :P

Many games did in many ways, probably the last one has been Braid

i will changed my life not game just me :)

Terranigma, it was the first game that really hooked me up. Before that, I basically had played only platformers, and for my age the game was a real challenge. I found the story amazing and I didn't stop playing untill I finished it.

Ragnarok, i got the pleasure to have known so many good people who still are most of my best friends, was a great time and i really enjoyed it. By far the biggest change that any game did for me.

secondlife found my secondwife there lol

Runescape back in 2004. I used to be a straight A student in a gifted program until I started playing games...now I barely made it into a 4-year college and am still procrastinating all the time even though I tried for 2 years to change my habits...

minecraft
it's such shit i'm crying every morning

Just Cause 2. I was interested in the game, and one day, I discovered that there was a demo on Steam. Created an account, downloaded the demo and loved it. A few weeks later, Just Cause 2 was on a sale 75% off. I didn't hesitate much, and bought it. Without Just Cause 2, I would never have discovered Steam, and without Steam I wouldn't have discovered Steamgifts. And that's one thing I definitely wouldn't want to have happened.

Hmmm i think Unreal Tournament 99 it was first multi-player game which allowed me to say bye bye to Quake I after about 4 years of playing quake I.I also meat many great people in those days...One of them is my girlfriend :)

Kingdom Hearts. It was the first game that really had a good story and since then I have been paying a lot of attention to stories of games.

Baldur's Gate II.
This game alone had me spend countless hours on D&D and p&p roleplaying.

Portal. It was the first 'game' I had played, back in 2011, and through some other events after that, I find myself throwing hours and hours into programming, 3D modelling, traditional art, music, cinematography, and Steam.

Rock Band

MGQ

Half Life. It was the first real shooter I played (meaning not Star Wars) and what got me into FPS.

Final Fantasy 7. Made me learn soooo much english, plus wow what an awesome history :)

Trine 2... made me aware of that games are more then just visuals :P
