If you put AA2-2 in the first game (The weakest case here IMO) It would STILL be the second best case in that game. I cannot underestimate how much of a true step up this game is. It's SO GOOD.
Tactics were a great idea honestly, I know that's controversial but yeah. Second half is one of the best gaming experiences I've ever had, first half is still amazing but a few eh moments. I recommend this to any teen.
