They turned a good game on mobile into a predatory mobile game
I love the original PvZ. Art style, level design, gameplay, the extras, all excellent.
Then 2 came out, and it threw all of that in the bin. And yet somehow, they've made it worse with this game.
Think of every awful mechanic from mobile games that are different from their adverts and you'll be pretty close. Plants require upgrading using multiple in-game currencies. Plants require unlocking via multiple in-game currencies. Some are behind a regular monetary pay wall. You have a "home base" where you can grow plants to get some of the resources needed to upgrade and unlock more in that type. But guess what, you guessed it, more currencies required to grow them.
And of course, no trash mobile game is complete without an energy meter that refillsin real time, communities with other players (you're penalised for not being in one), a star rating and rewards after each level, a premium pass, and unnecessary cutscenes.
Everything made the original the incredible game it was has been mulched and processed beyond recognition, including the art style and mechanics. The merge mechanic is just worse than the upgraded plants from the first game. Especially when the merged sunflowers go from producing 50 sun at a time, to 52. Fifty-two!? At the same rate.
All around abysmal, money grabbing game.
