The "Perfect" PvZ 3: Evolved.
My idea of the perfect PvZ 3 would be making PvZ 3: Evolved a paid game (like the original Plants vs. Zombies 1) where everything is included or can be unlocked by playing, and obviously without microtransactions or absurdly overpowered, ridiculous, or weird plants.
From PvZ 2, I’d take the variety of plants and zombies and the plantfood system.
The fusion mechanic is very good, so you don’t have to overcrowd the game with plants like Repeater or others that are basically just combinations of two plants. I also really like the house decoration feature, but I’d expand the costumization even more (like adding accessories for plants).
Anyways, is REALLY HARD to unlock new evolutions/fusions (almost impossible without paying a lot).
It should be A LOT easier.
All of that combined with a silly but fun story like in PvZ 2, and a campaign mode divided into worlds like in PvZ 2 (and with similar difficulty), but with more variety and everything mentioned before. (As i have seen, this game will have more "worlds" in the future, so that's good!)
Also adding minigames in some levels would be cool! Like in PvZ 1 or 2.
One more thing:
The fact that the early access of this PvZ 3: Evolved includes a “3-star” system per level makes it feel like a low-quality, generic mobile game.
And that would be it.
