Whew! That was a lot of work.   

SMG: 4.40
TP: 4.33
MP8: 4m
SPM: 2.01
RE4: 1.3
MP3: 1.05
Cooking Mama: 0.57
Trauma Center NB: 0.10

Total: 17.76m/8 = 2.22

( (2.22/19.45)x10) = 1.14

W00t. MoH:V wasn't listed with sales. :(

I need to get Wii Play though, will definitely jump me up, and Mario/Sonic. :b

my score 1.25.

i think it's a bit unfairly low though cause i am pretty mainstream in my gaming. zack and wiki and trauma center new blood lowered my score a lot. that and some of my most pop titles (wii play, mario galaxy) are going to sell a ton more in the future and that would raise my score.

obviously this comparison has flaws. Without buying a single game, your number will change, but at a given instance in time it gives us an interesting picture of how "mainstream" your purchases are. Obviously one of the bigger flaws is that if you buy a popular game before it becomes so your score will be lower (M&S, MP8 for examples)

I don't know why this thread crossed my mind but it did. Looks like I'm more mainstream now with the Wii, and there really aren't many replies to compare the DS too.

Super Mario Galaxy - 6.72 M
Super Smash Brothers Brawl - 5.97 M
Mario Kart Wii - 6.04 M
Boom Blox - 0.25 M
Trauma Center: New Blood - 0.14 M
Trauma Center: Second Opinion - 0.53 M
Super Paper Mario - 2.39 M
Mario & Sonic at the Olympic Games - 4.68 M
The Legend of Zelda: Twilight Princess - 4.90 M
Zack and Wiki: The Quest for Barbaros' Treasure - 0.38 M
Harry Potter and the Order of the Phoenix - 0.20 M
Excite Truck - 0.62 M
Rayman Raving Rabbids - 1.37 M

Total WW = 34.19

WW/# of games = 34.19/13 = 2.63

2.63/28.46*10 = 0.92

I am less than mainstream. Woohoo!

I know I'm mainstream and I never read the OP by the way as well blar.

How? Well simple - I like good games and quite a few of them have been released.

Guess what I'm mainstream. ^_^

it would take me ages for mine, i have 32 xbox 360 games, 16 ps3 games and 8 Wii games

I'm almost certain I have more or at least a lot of current gen games over a lot of people here.

I didn't list them all on VGC though.. that would take too much time.

Basically

Wii: Around 47~50 +Wii Sports and Links Xbow training

PS3: Around 9 Now since I bought MGS4

PC: I down load games - not sure if that counts, but their usually mmorpgs.
