This is my first blog. Ever... What I want to output is my top ten games, as stated by the title of this topic. These are all based on their single player modes. I don't necessarily rate games that are online.
1. Prince of Persia; Sands of Time
2. God of War
3. Dreamfall: The longest Journey
4. Star Wars: Jedi Knight 2: Jedi Outcast
5. Prince of Persia: The Two Thrones
6. Gran Turismo 4
7. Curse of Monkey Island
8. Lord of the Rings; Fellowship, Two Towers, Return of the King
9. Jurassic Park; Operation Genesis
10. F.E.A.R.
Not that these will change, due to upcoming games and changing preferences.
