Poki software, Poker Acadamy, Stacked..........Opinoins, reviews?

[Zachvdp]

I was wondering how good Poker academy is? is it worth it?
seems pretty cool to play a bunch of hands with some competetion for free.
Also i saw that the game "Stacked" was built on the same Poki software and it got pretty good reviews on some sites, a better score than any other console poker game, any one played it? Any one know about the Poki soft ware?
From what it read, it seem to constantly change it's play, depending on you play. The reviews say you can abuse the all in feature, making the computer fold pretty much every time you go all in. But if you play for real you get some "solid?" competition.
Just wondering if any one has any experience with the Poki software, positive or negative.
