Yes it's great! Especially the achievements system take the game to the next level! I also really liked the fact that
Sabotage,
Avenging Angel and Nature have been restored.
The only thing that I have concerns about, and maybe I won't like it, is the simultaneous games against a player. I usually host games and want to play against different people and different decks. If the new system means that somebody will hog my hosted games... well I don't know. We'll see.
Also, I have a question: What are those "in-game awards" that I read about in the Updates thread? I can't find something about it in the manual. Is it related to the achievements?
Keep up the good work!
