Minecraft is the holy grail of sandbox games. What initially appeared to be some ugly 8 bit game with basic functionality has become one of the most complex and creative games on the market at the moment. It didn’t become one of the most popular games for streamers for nothing.
The bottom line for Minecraft is that it is like nothing else. It became so popular because it was fresh and new and remains popular because it did everything perfectly that there isn’t much a competitor could do to change this. With that being said, there have been many attempts to make games like Minecraft.
Ive seen some on the Google play store before that look the exact same and end up being fake apps that look nothing like the screenshots. With the success of the game there are bound to be some good games out there that are like Minecraft.
