Minecraft is a simple sandbox building game. It has gotten insanely popular over the years, though. and it seems there is almost no limit as to what you can build. You can be in three modes. Creative, Survival and Hardcore. In Creative, you can fly and basically never die and you can get basically any block easily. In Survival you have a limited amount of health, can't fly and have to get your own blocks to make your own house and survive mobs. Hardcore is the most intense. If you die once. You lose all your data (on that server. Not the whole game of course.) Some people make Minecraft youtube videos and some are really popular. Such as ExplodingTNT, CaptainSparkles etc. Also, some people choose to compare Minecraft to Roblox because some people think they are similar.
Popular Minecraft Youtubers are somewhat like this:
CaptainSparklez: Hey Everybody!
Fan: OMG I LOVE YOUR VIDEOS!
