Short Version: Do not buy this game. If you want to play Magic at your computer without investing in MTGO, buy DOTP 2014 instead.
Quite frankly WOTC isnt known for quality control of digital products, but this might actually be the worst designed product with their name on it that I've seen (and I played MTG Tactics and MTG Battlegrounds). I finally decided to try this version out, despite all of the negative things I've heard about it. Surprisingly though, its somehow worse than I expected.
The microtransactions arent the real problem here. Certainly they are there, and that is slightly annoying given that the point of the DOTP franchise is to play MTG without that aspect of the card game. However as a paper MTG player I'm certainly used to that.
No, the real problem here is that the game that you are paying for is garbage. First of all, its one of the most abysmal PC ports I've seen in awhile. Instead of a menu screen, you get a series of icons that you scroll through one at a time until you find the one you were trying to get to. Even in game, the mouse controls are strangely less smooth and not as responsive as in 2014. It feels like the function of every aspect of the game has been sacrificed to try to make things look "cool".
And since I'm talking about the appearance of the game. It looks horrible. Why is everything on the screen black and grey? Did someone at the studio decide that the colorful blues, golds, and reds of DOTP 2014 were too pleasant to look at? The whole design of the in-game interface is not only far less convenient and poorly laid out, but also just plain irritating to look at. Are me and my opponent playing MTG in some dystopian sci-fi future where joy is illegal?
But so far I've been talking about the interface, gameplay functionality, and apperance of the game; "what about the actual card game?", you excitedly ask.
Unfortunately its just not worth it. I continuously feel as though Im playing the sealed gameplay mode of DOTP 2014... except with less interesting cards. And this is the 2015 campaign gameplay. Sure being able to make my own deck with random cards is nice, but if I wanted to make a crappy deck with crappy cards I would play sealed mode. Which I can already do in DOTP 2014. And if I want to play multiplayer or the campaign, 2014 lets me play with some fun Magic cards from throughout MTG history instead of the boring trash you get to work with in 2015.
In conclusion, if at any given time I was unable to go out and play paper Magic with people in person, I would play DOTP 2014. If I was unable to play DOTP 2014, I would play Hearthstone. And if I was forced to play DOTP 2015... I would go read a book.
Learn from my mistake, dont buy this version of DOTP. Dont support their horrible decisions. Hopefully WOTC will seriously rethink their poorly implemented digital business model.
