So I had been thinking, there are 4 modes, Peaceful, East, Medium and Hard.

I figure that is not enough.

In addition to those modes, 3 new ones should be added and a few changes.

Firstly, you should never die on Peaceful. Lava, drowning, sufforcating, and falling will not kill you, and will only get you down to the very last of your health. If sand falls on you or anything and you can't move, you are teleported near the mound or away from it so you can't suffocate anymore. Mobs are not spawned, unless you spawn them first, and they cannot attack you back.

The first mode, should be "Novice", which is a mode more for players who are new to fighting and surviving against monsters. These mobs are a bit weaker than Easy mode monsters, and are really easy to kill, but loot is VERY less often to get since you can kill them in less than two or even a single blow.

The second of course, is "Easy". Mobs are easier to kill, but are harder than in Novice.

The third is Normal, which is default.

The fourth is Hard, which mobs are harder to kill, but loot is greater to get. Creepers explode 2x worse.

The Fifth mode is Very Hard, which Mobs now begin to wear armour, and get pretty intelligent. Skeletons can open doors, and switch to Melee. Creepers can now teleport to your position if you run away and even explode behind you. Creeper explosions are 4x worse than usual, PLUS mobs can spawn 10 blocks away from a torch.

The Sixth Mode is Nether. Mwhahahahaha... and you know what this level means... good luck, mortal.
