More Princess Needed!

Mental image of those girls hopping on one foot screaming "ow ow ow" and a devious merchant offering to sell them shoes.

I'm not familiar with the others, but as for Rapunzel not having shoes, it's a visual reference to her prisoner status.
To explain, in prisons, it's common to take someone's shoes away for a simple reason, you'll hurt yourself walking over the rough terrain surrounding the prison, which will slow you down and make it easier for the guards to catch you, as you won't be moving very fast.

Yeah, Disney Infinity does appear to be lacking a bit for the girls, mine loves Violet though and is super excited for:
Jesse and Vanellope, and Perry (Agent P).
I know Ariel would be a welcomed edition, like others here I tend to think the lack of a power disc means a better chance of a playset or standalone figure.

Ursula and Malificent characters......

I might just feint.

If we're mentioning non Princess females too... then Calhoun please.

^Sounds cool.
I for one would love to have merida.

^Yeah, actually surprised they didn't make Merida a playable character anyhow. lol

Been wanting Merida from the start - I would LOVE to see the other princesses also, but the issue is most of us want a playset, and either they have to choose just 1-2 princesses to give a playset to, or they will need to try and find a way to give them all a single playset to work in (Which I believe they have a world where bell, aurora, and cinderella)

The next biggest issue is that they still don't want to scare the boys away by making it all girly (seeing as how the game is supposed to be for everyone) but they are verging on scaring the girls away by not having any particular storyline that is meant to be appealing to them

^ My niece only likes to play with Jessie. LOL. Like she doesn't play video games, she only watches my nephews play, but for the Toy Story 3 game she made an exception because she got to play as Jessie. She will probably only play with DI when I get the Jessie figurine.

And I wouldn't mind seeing a Sofia the First figurine too.
