When I was young, I could skip sleep a couple of nights in a row just to play. Sadly, I have to give gaming low priority nowadays. Anyway, the games I've played the most are Civlization I-IV. There are 8 765.81277 hours in a year, and it's not impossible that I've spent a year of my life playing these games. I don't regret it, because as far as I'm concerned, Civilization is the Rolls Royce of computer games. The games which gave me the most immersive gaming experiences are Knights of the Old Republic I and II, though. As a Star Wars fan, it's impossible for me to not love them by all my heart.
