Minecraft is a sandbox game. In this game you can build amazing creations (using blocks). The game modes are Creative, Survival, Hardcore, and Adventure. You can play with your friends. At night, Zombies, Skeletons, Spiders, Creepers and others come out at night. You can kill those monsters. When you kill them, they drop resources. You can make houses, castles, monster traps, you name it. On survival, you have to mine for almost everything. On creative, you have unlimted stuff. On hardcore, it's just like survival, except it's WAY harder. And Adventure mode, you can't break any blocks. This game is better then Roblox.
