What Are Your Favorite/Most Played Games of all Time?

So gamespot, what are the games that you loved so much that to this day you could pick them up and play for hours?

A top 5 or 10 would be great, heres mine.

1. Starcraft: Broodwar (PC) - I have put hundreds upon hundreds of hours into this game. Starcraft 2 Alpha Will be worth buying a new pc over.

2. Dark Cloud (PS2) - No RPG can compare to it imo. This game has been played through over and over again.

3. The Legend of Zelda: Ocarina of Time (N64) - This game defined my childhood.

4. Call Of Duty 4/World at War (PS3) - Both are essentially the same thing, pure fun.

5. Super Smash Brothers Melee (N64) - The best game to play with friends no doubt.

6. Metal Gear Solid 4: Guns of the Patriots (PS3) - Simply epic.

7. Super Mario Brothers/Duck Hunt (NES) - Can't go wrong with it.

8. Goldeneye 007 (N64) - another classic.
