I don't know if I just got 'lucky' (or rather, unlucky), but in ~4 hours I had completed this game. I'm talking about every level unlocked, every minigame unlocked, every multiplayer unlocked. The only thing I haven't *totally* completed are the 'Pose Cards', which... well, they're pointless, as far as I can tell, because you can do nothing with them, at least compared to the 'toys' you got in Twisted that you'd play with for 5 seconds at least. Perhaps this is why there's so much debate over whether its short or not-- some of us get all the games in order, some people play 40 times over and still can't get that last game.
Don't get me wrong, I'm still enjoying this game, but I totally agree with those who think it's too short compared to previous wariowares. It used to take me ages to complete them-- Even on a second playthrough on twisted it took me several hours (I'd say at least 6 hours, been playing in 2 hour batches over the last few days before this came out) to get nearly everything unlocked. It's still fun though.
For those who are at the point where I am, where there's really nothing left to unlock, and you're looking for a little more replayability, some of you might be interested in something I mentioned in the Wii Sports thread before--
Cyberscore.
It's a high score competition site. It's got
smooth moves on there (as well as the previous wariowares and loads more), so you can compete for high scores in either the Character Levels, the minigames like
Tower Tennis, and the various mixes. It's given me a little more inspiration to keep going back to it, at least. It's the only thing that's made me play since I completed it really, so hopefully someone else might find some use in it too.
