Here are my rankings on the PvZ Games, I am going from least to most liked and will provide a bit of a description on each:
6. Plants vs Zombies: Garden Warfare 1.
I had not heard that much about the game back before its sequel was released and I was not particularly into shooters either. I know much more about this game now and when I compare it to Garden Warfare 2 and the content and changes that its sequel gains, I would much prefer its sequel. Might try this game at some point though!
5. Plants vs Zombies 2.
I cannot rank this game properly, as I have not had a chance to try it out. Looks really good and promising though - and apparently it is still receiving updates!
4. Plants vs Zombies 1.
An awesome, classic game that I have played ever since before I was a teenager. While it is an old game and I do not play it that much right now, I still really like it and still play it from time to time. The Zen Garden is cool. I wonder how large the Tree of Wisdom can get as well? There is still stuff I want to find out! Or I could check the Wiki? No thanks!
3. Plants vs Zombies Heroes.
This card game is a lot of fun, it is a free game, and I play it daily! You can jump on and do quick battles with Al or you can climb the ranks by defeating other players! There are a lot of missions to do, daily challenges each day and unique decks you can create! Also I really like card games in general!
2. Plants vs Zombies: Garden Warfare 2.
Variants are a lot of fun to use! You did not have all the variants unlocked from the start, meaning you had to earn them, which I liked. Each variant had their own upgrades, even if the upgrades were more basic in this game, that you were able to use and interchange between variants. Some variants had unique upgrades. The maps were awesome, I absolutely loved Boss Hunts! It goes on!
1. Plants vs Zombies: Battle for Neighborville.
The character upgrades, especially after this recent balancing patch, are a lot of fun to use. It allows you to buff your character in the way you like. They really expanded on the upgrade system in this game! Awesome! I also really enjoyed the Legendary Upgrades. While the maps were not particularly as great as the previous shooters or Ops, the letdown is not that significant. Still annoying though. I love the upgrade variety though. And the Prize Maps.
