Minecraft's biggest problem is that it doesn't have any goals and end.Even though killing Ender Dragon can be counted as finishing Minecraft,nothing really happen before or after.
I played creativerse for a while and its basically minecraft on steroids and f2p.I like this game more cuz of concept of glove mining every resource and layers of blocks containing different mobs and ores,and the lower you get the higher the reward and the danger is.
But it became boring the moment I got the best ore,much like in minecraft you craft diamond pickaxe,sword,enhance them and boom you are done.
Also building is useless because you earn nothing from your house not being a dirt cube.
I kinda liked spore more because it has rpg elements and actual goals and rewards.
