I've been playing Harvest Moon 64 off and on in the past few days, but I think my game pak is starting to get old. It resets at random times when I play it. Kind of depresses me.
The last game I really got into was Metal Gear Solid 3 about a week ago. I had a really strong urge to play it, and I beat the one game that I saved, and then beat it in seven hours the next day with eight alerts and a couple hundred kills. I still might go back and play it again; I think I need to beat it twice before I unlock the secret cinema thing. Playing it has only made me realize that it is probably the best story ever told in a video game.
In other news, I'm also thinking about going back and replaying Persona 4. Another game with an amazing story, though it just never got as fun as Persona 3 did.
