what i think goes over people's heads is that this is just for fun and a good chance to re-live old days with a twist, its not meant to hurt/demean PVZ, I'm sure the guy woke up and thought "this seems fun, ill make it and see." I get the whole copy right argument, but it really isnt that deep, I dont think hes gonna get rich off of this, so lets just enjoy it. A video i found literally says Plants vs. Zombies with a rougelike twist. Thats all this is. you seem the type to complain about any good thing in your life.
