My favorite two games

The Long Dark           

The Long Dark is one of my favorite games on Stream. The background of this game is that you are the only survival in an air crash, and land in north Canada in winter. You have to keep searching resources to survive. You are surrounded by hunger, thirst, beasts, and cold. The reason I love this game is that everything looks so real. You have to find dry wood to make a fire, so you can boil drinkable water. You can also eat snow, but that could make you sick, and then you have to find medicines. You must calculate everything like how long you can sleep, how long you should spend on searching food and fuel, how to make a shortest detour to avoid wolves’ and bears’ attack, etc.

Plants Vs. Zombies

Plants Vs. Zombies is also one of my favorite games. I feel all the plants and zombies are so cute. The plants have cadence with the rhythm of the background music, and the zombies are designed very creatively like there are MJ zombies, football zombies, snorkel zombies, etc. This is a fun game but also full of challenges. You should not only fight zombies in the day time, but also in night, in fog, and on the roof fighting Dr. Zomboss.
