Asking them to fix stuff that you bought for 1.0 and make it viable for 3.0 without having to pay for it again... well, that's almost as bad as a cash grab.
And you can't argue that the new mickey has a whole new move-set so that's not a cash-grab, but then call re-tooling vanellope and giving her completely different combat abilities and super moves a cash grab. That just...makes 0 sense. That's pretty much EXACTLY what the new mickey is.
I think it's incredibly generous of them to keep supporting the old generation toys in the new platforms. I can only imagine them scratching their heads and muttering about the fact that they still let the players use their first version toys in the third version of the game, yet that's just not good enough for some people.
