Sure, it may be a dumbed down version of the card game, but by focusing on action and strategy the game becomes much more accessible to casual gamers and those who aren't already hardcore fans of the card game.
I've played so many "Warcraft III" clones recently that it's really refreshing to cover a game that's actually doing something innovative. However, it's the online and VS games that really flesh out Battlegrounds, since the single-player experience is pretty flat.
Two steps removed from the CCG it seeks to emulate, and is unlikely to appeal to anyone but Magic aficionados - and even then it has so cruelly crushed the freedom and essence of the licence that players of 'chess with cards' cannot help but shun it.
There are definitely some hurdles you'll have to get over to enjoy this game, but there is certainly fun to be had. For me it was the strategic, puzzle-like single player mode, but for others it may be the ability to alter decks and play against online opponents.
There is so much game packed in here because of what it's based on that you could literally get lost inside of it. But I hope you get the gist of how the game is played. It's totally a thinking person's game.
The mediocre graphics bring the quality of the game down somewhat, and, while the need for frantic strategies will probably keep you playing, the lack of any sort of selection of different game modes may reduce Battlegrounds to being a rental, at best.
