This doesnt include Zelda TP as my original Wii Broke. On the in game clock it took me just over 40hrs to complete so thats definitely my No1.

you dont want to know mate... lol because most of the games i have played is not accurate because sometimes i let it sit their for hours and not playing it. ill show ya for example my top 5 is....

Donkey Kong Country Returns "596 Hrs 39 mins, 5 times"
Wii Shop Channel "553 Hrs, 38 mins, 96 times"
No More Heroes Desperate Struggle "156 hrs, 52 min, 8 times"
Golden Eye 007 "92 hrs, 49 min, 9 times"
Super Mario All Stars 86Hrs, 47 min, 5 times

i left my wii on over night forgetting to turn it off when im still in gameplay... only Wii Shop channel is accurate

You spent 553 hours on the shop channel?

I have checked the ranks of Wiiware and VC games almost every week for multiple PAL regions since mid 2007 and have still not managed 1/4 of that.

Wow, you guys are so undevoted to gaming, xD. (Or maybe you just have lives...)
Mario Kart Wii - 1144h9m 146 times
Wii Sports - 498h42m 69 times
Super Mario RPG: Legend of the Seven Stars - 429h49m 7 times (haven't even finished it yet, mind you)
Sonic and Knuckles - 404h19m 30 times
Super Smash Bros. Brawl 355h9m 78 times
After that, it slopes with NSMBW at ~250h, Epic Mickey at ~225h (not even halfway), Paper Mario at ~125h (halfway through), Chrono Trigger at ~120h and Pokepark at ~90h, with everything else at or well below ~50h.

And here I thought I preferred handhelds (though, admittedly, Pokemon Emerald is prolly at least twice MKWii)...

How do you play a game like Mario RPG for 429 hours and not finish it?  It's not that long of a game!!  Even Chrono Trigger hasn't even been out that long (and it's short with consecutive playthroughs being even shorter since your weapons/levels carry over)!  And your Mario RPG playthroughs--7 sessions at almost 430 hours!  Even if you played it and left it on for a whole day, you'd average 60+ hours a day!!

Rune Factory Frontier - 241 hours
Super Mario Galaxy 2 - 223 hours
Animal Crossing City Folk - 219 hours
Super Mario Galaxy - 123 hours
Wii Fit Plus - 122 hours (Although it would be 202 hours with Wii Fit added)

Well, there's that, partially (for, say, Epic Mickey and Pokepark). But for, say, SMRPG and Paper Mario, I just spend far too much time grinding and trying to increase my level (though with 60h per playthrough, that obviously took place as well for SMRPG when I wasn't playing it like a lunatic). As for MK and the like, I just play too much.

I honestly don't waste that much electricity, :O!

Looking at it, I had to have left my Wii on for SMRPG, even if I do recall a bit, err, long, play sessions. And CT, since it just released, I'm sure I definitely spent that much time on (still haven't beaten Lavos even once). I just grind a lot.
