(yes, all current generation titles cause I didn't play many games until I was done college... opposite of most people lol).

That's a tough one. I don't think there really are five games that could alone satisfy me. I guess something like Tetris or Columns or Puyo Pop are timeless and infinite, but those kinds of games are only good for short plays. I wouldn't want to play them everyday for the rest of my life. Nor would I want to play any game or five games for the rest of my life. I don't really like multiplayer games so something like WoW or online shooters wouldn't be for me either.

I guess I'll go with these for the reasons listed below.

Portal 2
Fan made mods and levels could keep it entertaining for a long time. Every few years I can see myself replaying it for the story like I re-watch a good movie. It has the best of puzzle and action games. Puzzle games are timeless and good action games don't get tedious.

Halo 2
I've nearly played Halo CE to death even though it's still my favorite Halo game. Halo 2 has a more interesting story, more environments, and you get to play as the Arbitor which I've always loved. I almost put Halo 3 here but if I had to choose just one I had to go with Halo 2. If I could I'd put the whole Halo series here because in my opinion they go together all or nothing, but I can't live with no Halo so Halo 2 it is.

Panzer Dragoon Saga
It's the best JRPG ever made. I can see myself playing this every few years like I watch a good movie. My current favorite RPG is the Mass Effect series, but I can't choose just one and I'd hate to never play PDS again. If I could do series instead of single games then Mass Effect would win out.

Zelda Ocarina of TIme
It's still my favorite and I can see myself playing this once a year or at least every two years.

Forza 4
Racing games are great slow burn games. You can play them for years and years and never master all the tracks to perfections. Forza has the added bonus of letting you fully customize the cars so even if I got bored with the races I could paint cars forever.

Civilization 5 - fully expanded this is a monstrous game with tons of potential.

Minecraft - Guess why

Xenogears - my favourite story in an RPG with many favourite characters.

Final Fantasy 8 - my favourite world with my favourite towns, lots of depth and customization, one I love replaying, and in my opinion, it represents the very peak of Final Fantasy; but I will miss 6, 7, and Chrono Trigger greatly.

Skies of Arcadia - I just love this game, I love going through it, making discoveries, gathering a crew, building up my town, etc... I would never want to part with this game.

These three RPGs are my three favourites; I would love to have Earthbound, Dragon Quest series, Xenosaga, Mario games, Zelda, and many more - limiting to 5 makes it difficult to justify beyond the games I have listed.

final fantasy 7,8,9,10
some pokemon game.
only games ive ever played more than once.

Black Ops: Really addictive online play that has had me coming back for over a year now

Super Smash Bros Brawl: Great game with friends that never gets old



Honestly those are the only ones I can think of right now that wouldn't get old quickly, I'm surprised by the number of people listing games with mostly a single player story mode.

Donkey Kong Country
Donkey Kong Country 2
Super Mario World
Mario Kart 7
Resident Evil 4
