1. Final Fantasy VII. Fave game of all time and have completed it a dozen times. Last time was a couple of years ago and I refused to complete it without defeating all the weapons beforehand.
2. Metal Gear Solid. The first one on playstation was a real masterpiece. Great, original story with fantastic gameplay and that had a fascinating way of blending in real world political events.
3. Football Manager, simply for how many hours of my life I've spent on that game!
