Plants vs Zombies vs Viridi
Plants vs Zombies
Plants vs Zombies is a whimsical tower defense game that places you in a unique position, mainly by planting a wide variety of plants on your lawn, to counter the advancing horde of zombies that are about to invade your home. You'll gradually expand your troop of potted plants as you progress to increasingly challenging levels and you'll need to adapt to the game as its situation changes, such as defending against the horde on your roof or at night. The coins you've earned from playing levels can then be spent at Crazy Dave's shop which he ran from the back of his van. There's even a mini-game of sorts where you can plant and harvest a variety of items, including coins, in your own garden.Proclaimed as being one of the modern classic tower defense games, Plants vs Zombies (PvZ) set a high bar for other similar TD games to follow and from what we can see, only a handful (Kingdom Rush, for example) managed to make it to a similar level of popularity as PvZ has enjoyed. PopCap Games has even followed up PvZ's huge success with exciting sequels (only on mobile though) and equally-entertaining spin-offs, like the PvZ: Garden Warefare game which diversified the entire franchise by delving into the competitive shooter genre.
Viridi
Viridi has been hailed as one of the most relaxing game on Steam, though the game is now available on both Android and iOS now as well. How can you relax by playing this game? Well, Viridi is basically a plant simulator; a safe haven where you can patiently take care of a large pot of plants that are often arranged decoratively to resemble something you might see in a terrarium. The game is not intended to be played in long periods of time. Just like a real life plant, you simply need to check in once a day or so, water and maybe fertilize it, and leave it to grow at its own pace. If you do a good job of caring for your plant, it might even flower for you (as long as it's a flowering plant)!Viridi is a limited free-to-play game which makes it more of a free-to-try. There are some free plants you can play around with for free, but if you want to really get into the game, there is an assortment of different plants in the in-game nursery that you can buy with real money. You can also get a free seedling every week.
