What are the games with the shortest playthrough that kept u asking for more!!

I'll start with lord of the rings the return of the king, I finished it with every character all the missions in the first day I bought it.

and almost all MGS games are kind of short too :S.

Uncharted, mirror´s edge and MGS4.

Ico is the first game that comes to mind. It's so sad that that game is only 5 and a half hours and yet so awesome.

I think Uncharted and Infamous for me. Ratchet and Clank TOD sort of too.

But the 3 games, Ratchet for in game "trophies" and the other too really extended the replay for me enough to satisfy my purchases.

Batman: Arkham Asylum. I felt so sad when I beat it. I just wanted it to keep going

My first run through of MGS4 was 17 hours, by far the longest MGS I've played. Even on my second run through, knowing where everything is, and where to go, I'm still approaching 15 hours.

I know you can bolt through the game and finish in like 5 hours (somehow), but then you're not really playing MGS4....
