DO NOT BUY THE COMPLETE VERSION!!!
If you pay the $35 for this game, you will be paying to skip content. Winning games to unlock boosters is the whole point of DotP, so buying the complete version basically means you've wasted not only the extra money over the basic version, but also the money for the basic version. All. Your. Money. Wasted.
The "pick a deck, but you're stuck with it" gimmick is bad design and the devs are bad for doing it. No preview of the decks, just a vague description that in my case was totally misleading. I chose Red->Black which was described as "focusing on stealing your opponent's creatures and sacrificing them for fun and profit". Yeah it was just a plain RB aggro deck with 2 Act of Treason and 2 vampires that could sacrifice creatures for a +1/+1 counter...in a 60-card deck. 4 cards does not a focus make.
But that bad design was merely irritating, not game-breaking. I could live with it.
The deck-building feature is good, it's about time that they added it. However, they didn't actually add it. They replaced all other features with it, for a net loss of game. Let's see what the trade off was for something that should have been a standard feature years ago:
No more Two-Headed Giant, either co-op vs AI or multiplayer.
No more Planechase multiplayer.
No Challenge puzzles.
No Sealed campaigns.
Is all that worth it? Hell no.
This is a blatant money-grab by Wizards, who clearly fear losing players from MTGO if they add too much actual gameplay here, which is completely stupid as the two games serve two different fanbases.
I have nothing but disgust for the design decisions of this game. Definitely do not recommend.
