I just got done with a period of gaming where I was just playing games I felt I had to. Games like Star Ocean, AOE Online and Mirrors Edge. They aren't necessarly frustrating or bad, but I just wasn't getting that 'addicted' feeling and literally feel asleep once or twice on them.
To get me out of this funk, I decided to go out and buy games I really wanted to play. Like Kirby's Epic Yarn, Red Dead Redemption, Valkyria Cronicles and Assassins Creed Brotherhood. And as a result, I'm having tons of fun and can't put them down.
Sometimes you need a little funk to make you appreciate the good games.
