So I was browsing a few games that I like on the Nintendo channel and found you can even view collectively how many hours were played meaning the entire community playing that game, here's a few that surprised me.
No More Heroes - 1.6 million hours played
CoD W@W - 6.7 million hours with about 50 hours per person.
Zack and Wiki - 800k hours (not bad for such a small userbase)
And this one is just hilarious (for a board game in the closet)
Super Smash Bros Brawl - 98 million hours played, played over 45 million times, with an average of 73 hours and 33 times played per person.
MaxwellGT2000 - "Does the amount of times you beat it count towards how hardcore you are?"
Wii Friend Code - 5882 9717 7391 0918 (PM me if you add me), PSN - MaxwellGT2000, XBL - BlkKniteCecil, MaxwellGT2000
