It's a game that you can learn lots of surviving tips from (might also be useful for Science)
Like, cutting a tree makes it levitate, or zombies exist, or endermen exist, or you can add a lava bucket to your invisible pockets, or making a sword requires no forging, or diamond can be mined only with an iron pickaxe, or how to make a nether portal, or you can build in air, or you can make a house that defies the laws of physics...
Tell me, what is science in this game, when the only science you can see are the existence of chickens and cows and even those are impossible to lure by simply flashing a stack of wheat in their faces, or a seed. And they breed by kissing, and takes less than 5 seconds to make a fully healthy baby.
Edit : Or that minecarts can make hard turns at a 90* angle, or that redstone, or electrical circuits will not electrocute humans who step on them, which are NAKED currents, by the way, and yet they power unlimited devices, or that everything can be made but a moveable car without the use of a mod, or that there are no birds, etc. etc.
Edit : Or that eating unidentified zombie flesh can make you hunger more, and not infected, or the matter that there is NO actual infection at all, and no bleeding out when shot with an arrow, surviving after falling 50 floors just because the fall was broken by a puddle, or that fishing only makes the fish visible when you caught it, wooden swords deflecting fireballs without getting burnt, planting cactus with bare hands, throwing stuff at a cactus and making it disappear, clouds that pass through buildings, a map limit, bedrock, moving skeletons, and rideable pigs who magically follow carrots on a stick, cows that can't get over 1 feet fences, creating a furnace takes rocks ONLY, digging straight down, digging stairs down without it caving in, torches that survive underground (No oxygen). Signposts that can hold up sand/dirt/ any block. Water can be places in one block and it flows down, it doesn't fall down, whilst staying still, stepping in lava takes 15 seconds to kill you, which actually takes only 3 seconds IRL, walking UNDERWATER without floating, walking underwater without submitting to the pressure, placing a plant underwater gives you air. etc. etc.
EDIT : The idea of creative mode, the idea of adventure mode, the idea of spawning after death, the idea of alternate dimensions being built on land by supposed "magical items"
Just what is survival and science in this game.
Play Forest if you want survival.
