I am not always in a mood for an epic from Square that is going to take me 40-50 hours to complete. Sometimes its nice to have a few games that are fun to just kill time with. Here a few of my favorites

Sega Marine Fishing - Gotta have the fishing controller, but this is one fun game. Nice new features like the training modes and building the aquarium give it lots of replay value and make it even better than the Bass Fishing game.

NBA2K1 - Sports games or probably the utimate quick fix and this is without a doubt the best sports game I have ever played.

Point Blank- Need a light gun, but this is one of the best light gun games I have played. Very addictive.

Tony Hawk Pro Skater 2 - I don't even like to skateboard and I love this game. Skateboarding as Spider Man is the ultimate.

Any of the fighting games would qualify I think - chief among my favorites being Soul Calibur, Dead or Alive 2 and Power Stone 2...

On the PS2, I can easily kill an hour racing down the slopes with SSX or running a few laps with ATV Offroad Fury. What a fun way to waste some time!

Ah yes SSX! Any good puzzle game as well. Super Puzzle Fighter, Pokemon Puzzle League, Chu Chu Rocket and Bust A Move.

Driver -- it's the only PSX game that keeps pulling me back every now and then, if even just to take a free cruise around the city and attempt to drive legally until the cops fire up their lights and siren. Let the pursuit begin!
