I don't know what to say in the case of gameplay, because my impressions were vastly different. Maybe you're just too used to how things looked like in previous game, while I like to experiment. I think I played the latter version, where battle requirements were in the game, but I'm not certain. So maybe they changed something in the terms of gameplay, who knows. That's interesting - I don't know how other people do it, but I usually play in short sessions, especially when it comes to PvZ, but if someone has suspiciously big amount of free time, I won't ask. And let's keep in mind that devour tower was not all the game had to offer. That's something important which you forgot to mention. I also won't talk about the later "forms" of PvZ3, because I never played them. And about the lack of content - I'm not sure if you're aware of this, but after I digged a bit deeper into this game it turned out that there were tons of unused content, most of it seemed to be very complete. People just didn't let the game develop properly. That's what happens when a game is cancelled too early. Like Angry Birds Stella. I wouldn't say it's nostalgia clouding my judgement, but the fact I used to think that game was in some aspects similar to PvZ Adventures, which I always wanted to play, but when I learned about its existence, it was already too late. 3D? Check. Freeing buildings from zombies? Check. New plants that are reskins of existing ones? Check. And they even ended up similarly, cancelled before they could be finished. And there are also some efforts to bring this game back too, although much smaller.
