I have all 3 systems, but theoretically if I only have a PS3 I would want:

Gears 1/2
Smash Bros Brawl
Star Ocean IV
Mass Effect
Tales of Vesperia

Gears Of war 1 and 2

I have a 360 and i really want to play MGS4!! But I dont miss any wii game...

360: Gears of War, but not nearly enough to actually buy one.

Wii: Metroid Prime 3: Corruption, also not nearly enough to buy one.

I get most of what I want with PS3 so I don't consider buying either other system (anymore).

I would like to had Mass Effect, and maybe Left4Dead..i dont like Gears (i am strange i dont like MGS also)

Nothing on the Wii

Is it just me or does quite a few people wanna play the vice versa of the HD consoles but 99% of us dont want anything on the Wii.....erm...no offence to Wii owners just thought im see'n some sort of trend here...

 yeah it amazes me how the Wii still outsells evrything hopefully that trend ends soon

Metroid and Zelda .... but there is no jealousy involved. I can certainly live and be extremely happy without playing those games.

When it comes down to it, 99.9% of Wii gamers would never come to a site like this. They bought their Wii for Wii Fit or Sports and whatever their kids wanted. The rest of us are the 1% of 360/PS3/whatever owners who are more than casual about our gaming.

The Wii is underrepresented here based on the demographic of people who bought the Wii.

There are some jRPGs coming for the Wii, and odd titles like No More Heroes make me not regret buying the console.

360 titles I envy are Tales of Vesperia and SO4 next year.
