just looked at the sales, wow.

The question is will anyone care?

dude, you're hidden in your head!

Yes, just. The problem is that it really doesn't seem to be sufficiently differentiated from the first game. It's called Wii Play: Motion, yet the first game had "motion" already. They should have gone with Wii Play 2 or Wii Play Plus.

wow, that's some terrible numbers for Wii Play Motion, I don't think it will hit a million after all :/

The game is useless without more interesting games supporting motion plus.
If there was a second wave of first party games coming for the peripheral consumers would have a reason to buy it. As it stands currently there is no reason, at least not until Wii U releases with some motion-plus games of its own.
I say it will make it to a million eventually based on brand name and momentum, but not much more.

I still think that few games are really nice and funny i have played more than any other party game on Wii.

The game is fine for what it is, a bonus when you buy the red remote plus. So if a new buyer wants an additional remote plus with their Wii Sport Resort bundle, they can get this - it's a better package than Fling Smash was.

EDIT:

That's also part of the problem. You'd only need a second remote plus or motion plus, if you wanted two player swords/cannoe/plane in Sport Resort (and I think everyone opted for the motion plus adapter). The future compatibility with Wii U is the other reason why some people would want to invest on these now.

Beginning of the summer, I've been playing with my nephew on Resort's plane and Mario Kart... having to attach and detach motion plus between each game, because he had to use the wheel. Wii U compatibility and this slight inconvenience has made me sell the old motes plus and invest on some remote pluses. Come November and I'll have 4 remote pluses bought for the same price I sold them, and a few more motion plus software to go with them (I've paid for each game additionally: Wii Play Motion 20 euros, FlingSmash 0 euros, Skyward Sword 37 euros). 

So, is Wii Play Motion worth 20 euros? I'd say so. Will it sell like it's father? No, but maybe it's son Wii Play U will.

Well a Wii remote plus coloured is £34.99 in Uk and Wii Motion Plus is £39.99 in HMV.

In Games teh Wii motion plus was dicsounted at £ 29.99 and Wii Motio Plus was £44.99.

So the game is worth it between 5 and 15 pounds in Uk.

Which i guess i correct since it is fun, very much but not full of play like Wii party for example.
