I've been playing this game nonstop over the weekend, and I love it. Good review, but I disagree with your comment here:
"Here, once a round has ended, of the eight cards you have, four are burned, and the other four go back into your hand. Because of this, you can never fully implement a game plan."
I think this is actually one of the interesting things about the game, because you CAN implement a game plan, you just often have to play for the 4th round to see it come to fruition. Or, sometimes the best course of action is to scrap whatever it is you're hoping to accomplish and play round by round. I've won both ways.
I find the AI to be pretty fun--it has a lot of different strategies, and some are pretty sneaky. For example, if you're not paying attention, they often amass a ton of money and then buy tons of points in round 4 to come from behind.
Anyway, just my 2 cents.
