I am a Resident Evil fan. I can play that game continuously without getting tired. I have the whole series and enjoy them year after year. There is a new one coming out next year; I will most like purchase it to complete my collection.
I cannot forget the starting days when i played games. It was during my 12 years of age. It is the moto race. Usually i have a fight with my friends to play it. I am sure i will enjoy it even now. But after that i have played so many games. The action continues.
I was addicted to World of Warcraft for a long time, but I find my work keeps me busy now, that and keeping up with all my other entertainment content. I still play Wow about 10-15 hours a week, but nowhere near what I was playing a year ago.
Castlevania: Portrait of Ruin. A lot of CV fans will say that it's one of the weakest DS titles, but even though it gets repetitive, there is a lot of replay to it. I've completed it a dozen times at least.
