4. Diablo 2. Craziest addiction. Ever.
3. Guild Wars. Redefined my view of MMOs. Over 1400+ hours spent in one summer.
2. Legend of Zelda: Ocarina of Time. The cupid's arrow to my gaming life.
1. Baldur's Gate 2: Shadow of Amn. Estimated 450 hours of my life, into a single player game. Need I say more? XD
