10 Minutes? Ugh.
I don't see the point of the first 25 seconds. Nor do I get it. And you don't really need a minute explaining how you saw the game a few years ago and didn't buy it. You took a little bit too long to explain the battle/cards thing. Maybe it is a complex system but I'm sure it could be significantly cut down enough to be quickly understood. You humour feels forced (see 2:20, 3:33) and throughout you sound like you're bored, as if this is some kind of chore. And also at 3:33, don't make a gigantic deal of something if you're just going to say that there's no real problem with it afterwards.
When you started talking about characters, the review became a little more interesting, and you picked up towards the end. A for effort in the fact that you made a Video review, a rarity around here.
Overall, too long and slow. Cutting it down a little would aid somewhat in my opinion.
Also, in the picture at 4:02, what the crap is going on?
