Looks great, the first was great fun and it seems this improves on that. I don't think I like the idea of people carrying all their items over from the first game - surely this means there will be a lack of reason to keep playing as the majority of things will already be unlocked?
I hate that it flipped the script. My two year old loves PVZ plants. To see it geared to the zombies, makes me think he won't be to interested but that's okay because I will get to play it alone for the first time. I feel that you have to be into it already though, I might give it a go.
