I think Plants Vs Zombies 2 was already released at first in China but when I checked it on Google Play, it says: "incompatible to all my devices."
So, I check on Google if there's an issue with my device, instead, I saw this link
Apparently, it's partially released worldwide, to Australia and New Zealand. Partial sounds misleading, and looking at the comments, a lot of people aren't still able to access the game on their Android smartphones.
I wonder when it will be released worldwide, I think the iOS version was released way earlier. I really want to play it when it comes out. Do you think it will be released soon? Are you interested in playing it? I think I might just play one of the similar games to PvZ for the mean time.
