Longest and shortest Silent Hill games?

[what]

I don't honestly know which really was longest or shortest for me.

All I can definitively say is that Shattered Memories felt the shortest to me, but this is because I played it through in two days' time. Usually, first playthroughs stretch out over many days for me.

^Yeah, you know if you could skip the annoying therapy tests, the game would be like 2 hr.s long. :/

If I am going of the first playthrough count:
Shortest: 0rigins
Longest: Silent Hill 4

If I am going by current playthrough count:
Shortest: Silent Hill (My speed run has clocked around 2 hr.s)
Longest: Silent Hill Downpour (though, I am only on like my 3rd playthrough.)
